Scientists from less-developed countries (LDC) perceive that it is difficult to publish in international journals from their countries. This online survey was conducted with the primary aim of determining the opinion of corresponding authors of published papers in international Pharmacology journals regarding the difficulties in publications and their possible solutions.
The titles of all Pharmacology journals were retrieved from Pubmed. 131 journals were included in study. The latest issue of all journals was reviewed thoroughly. An online survey was conducted from the corresponding authors of the published papers who belonged to LDC.
584 out 1919 papers (30.4%) originated from the LDC. 332 responses (response rate; 64.5%) were received from the authors. Approximately 50% the papers from LDC were published in journals with impact factor of less than 2. A weak negative correlation (r = -0.236) was observed between journal impact factor and the percentage of publications emanating from LDC. A significant majority of the corresponding authors (n = 254; 76.5%) perceived that it is difficult to publish in good quality journals from their countries. According to their opinion, biased attitude of editors and reviewers (64.8%) is the most important reason followed by the poor writing skills of the scientists from LDC (52.8%). The authors thought that well-written manuscript (76.1%), improvement in the quality of research (69.9%) and multidisciplinary research (42.9%) are important determinants that may improve the chances of publications.
The LDC are underrepresented in publications in Pharmacology journals. The corresponding authors of the published articles think that biased attitude of the editors as well as the reviewers of international journals and the poor writing skills of scientists are the major factors underlying the non-acceptance of their results. They also think that the improvement in the writing skills and quality of research will increase the chances of acceptance of their works in international journals.

Publishing in prominent scientific journals provides better visibility and impact of research results at individual as well as institutional and national level. Scientists are under continuous pressure to publish in international journals in order to obtain rewards and promotions [1, 2]. This also applies to scientists residing in less-developed (middle and low income) countries. Scientists from less-developed countries (LDC) perceive that it is difficult to get publications in reputable biomedical journals and the results of the studies in the fields of epidemiology , psychiatry , and cardiology  confirm the underrepresentation of LDC authors in the respective international journals. The conclusion of one survey indicates that researchers from LDC believe that the editorial bias against their works based on geographical location is a major reason for underrepresentation in publications .
In addition to quantity, the quality is increasingly recognized as a critical aspect while evaluating research. In the 1970s, some objective parameters were suggested as a means to evaluate quality of research [7, 8]. Among these parameters, the impact factor (IF) of the journal is widely employed as a tool to judge the quality of scientific research [9, 10]. The idea of IF was first coined by Garfield in 1955 . It is an instrument for the assessment of quality of the journal monitored periodically by Thomson Scientific (formerly International Scientific Institute-ISI), Philadelphia . Although, there are several criticisms regarding the usage of IF as a tool to measure the quality of publication [13, 14], it is still a very simple, convenient and quick indicator for assessing the impact and quality of research . Furthermore, this parameter is given a lot of weightage for recruitments, funding, promotions and rewards .
To date, no study has documented the opinion of scientists from LDC regarding the difficulties in publishing their work. Therefore, this online survey was conducted with the primary aim of determining the opinion of corresponding authors of published papers in international Pharmacology journals regarding the perceived difficulties in publishing their findings and the possible solutions. The secondary aim of the study was to determine the number of publications emanating from LDC in Pharmacology journals.

All the filled questionnaires from the corresponding authors were edited, coded and the responses were entered. As per the objectives of the study, the data presented are mainly descriptive. Pearson Correlation Coefficient was used to observe the direction and strength of relationship between the journal IF and percentage of publications emanating from the LDC. A scatter plot was also made to demonstrate this relationship.
As mentioned in the Methods, after exclusion, 131 Pharmacology journals were reviewed (Table 1). The total number of papers in all journals was 1919. Out of these, 584 (30.4%) originated from the non-OECD (hereafter referred as less-developed) countries. E mail addresses of 69 corresponding authors could not be retrieved. Corresponding authors of the remaining 515 papers were sent an e mail with an attached questionnaire. E mail could not be delivered to nine authors and five authors declined to participate. At the end of the study, 332 responses (response rate; 64.5%) were received (Figure 1).

This study has documented for the first time the representation of papers from LDC in Pharmacology journals and the opinion of the corresponding authors from these countries regarding the difficulties in publishing their studies.
The classification of the countries into developed and less-developed was based upon the membership of OECD. Those with OECD membership were labeled as developed and others as less-developed. The rationale for following this classification is that as OECD membership is restricted to high income countries as defined by the World Bank  which have an established democratic government set up . However, it should be noted that at the time of the study design, the membership of OECD was only 27, which has expanded up to 34 countries at the time of writing the manuscript. The data obtained from the authors of 7 new OECD members is included with other LDC.
According to US Census Bureau's International Data Base, OECD countries comprise only 13% of the world population in the year 2010 . However, this part of the world contributed more than two thirds of the total number of publications in Pharmacology journals compared to around 30% by the LDC. There were four journals; one each from China, India, Pakistan and Poland which published articles mainly from their own countries. This somewhat inflated the representation of publications from LDC. If we exclude these four journals from the analysis, the actual representation in international journals drops to 26.7%. Previously, publication rates of 4.8  and 6.0%  in psychiatry, 5.0% in tropical medicine , 6.5% in internal medicine , 5.5% in ophthalmology , 0.3% in anesthesiology  and very few in surgery  journals from LDC have been reported. These figures are grossly different from those presented in this study. However, there is a basic difference in the methodology of above studies and the current one. Previous reports have analysed only those papers that were published in leading journals with high IF in their respective fields. However, our study has analysed all Medline-indexed Pharmacology journals. Since we found that the publication rate from LDC is weakly but negatively correlated with the IF of the journal, the top ten highest ranking journals were analysed, separately. As expected, the publication rate from LDC markedly dropped to 10.2% in those journals, which approaches to already published reports. This finding is consistent with the response of corresponding authors; an overwhelming majority of whom believes that it is difficult to publish in high quality international journals.
In the face of the population size of the LDC, there is a gross underrepresentation of publications emerging from these countries. In order to understand the reasons underlying this underrepresentation, the corresponding authors were asked to identify them. Broadly, the reasons identified by them can be grouped into two categories. First, the reasons that are associated with the review process of the journals such as biased attitude and lack of trust among reviewers and editors on the data generated in their countries. In the second category, the reasons are associated with deficiencies prevailing within the scientists from LDC such as poor writing skills and poor quality of research. The former reasons were identified as the major hurdles underlying the non-acceptance of their publications by an overwhelming majority of authors. Indeed, there are some reports that have suggested that the data generated in low income nations is undervalued . Moreover, a statistically significant difference between the high and low income countries in terms of rejection rate of submitted manuscripts has been shown .
As far as the improvement in the quality of research in LDC is concerned, this is mainly linked to the political system of the country. It is known that research is the last priority in the majority of LDC with science being considered by governments as a luxury that can be afforded only by rich countries . Thus poor funding, lack of incentives to scientists and resources will eventually lead to poor research facilities, limited technical support and inadequate training. Obviously, with all these barriers, the scientific activities and research will be hampered. It is conceivable that under these less-encouraging circumstances, both quantity and quality of research would also be affected. Indeed, it has been shown that the number of submissions from LDC was far fewer (5.2% of the total submissions) compared to high income countries in psychiatry journals . As far as the other reasons identified by the authors are concerned, if these are valid, they can easily be resolved by the scientific community and the international journals. For example, one inherent reason is the poor writing skills of researchers from LDC because English is not the first language for the majority of these nations. Influential international journals with adequate human resources can come forward and offer a free service for checking and editing the manuscripts from non-English speaking scientists once they are accepted for publication. As a matter of policy, rejection of papers based on the inadequate usage of language should not be acceptable. International journals can initiate another measure to bridge this gap between the developed countries and LDC by reserving some pages for papers from LDC. This reserved section should publish the best research emanating from the LDC only. This would have a positive impact on the enthusiasm of the scientists. One case can be cited to reinforce this suggestion. The Journal of Pakistan Medical Association started a reserved section for students in 2004. This fostered an interest towards research among undergraduate medical students and student research groups at regional and national levels were made. Publications of their results as lead authors motivated them to involve themselves in larger projects. Recently, the undergraduate medical students have launched their own journal. Furthermore, notable scientists from the LDC should be invited to serve on the editorial staff of the international journals since presently, the majority of editorial board members of international medical journals are residents of highly developed nations [20, 28]. This step may help eliminate the feeling among authors from LDC that their findings are not given importance.
One limitation of the study is that the data was generated from papers published in only one issue of all Pharmacology journals. It is likely that these data may not be representative of the overall situation. However, the inclusion of all the journals in the current study has yielded a sample size which may be considered as sufficiently representative. Second limitation of the current study is that division of countries is based on the membership of OECD. This has put some high income countries like oil-rich Gulf States into LDC. However, this has been done purposefully because the academic history of these countries is rather brief. The third limitation is that Pharmacology related subject terms like antibacterial drugs, toxicology etc were not taken into account resulting in many journals that were not included.
The LDC are underrepresented in publications in Pharmacology journals. The corresponding authors of the published articles perceive that biased attitude of the editors as well as the reviewers of international journals and the poor writing skills of scientists are the major factors underlying the non-acceptance of their scientific work. They also think that the improvement in the writing skills and quality of research will increase the chances of acceptance of their works in international journals.
