PY - 2013 DA - 2013/09/30 TI - Recommendations for a uniform assessment of publication bias related to funding source JO - BMC Medical Research Methodology SP - 120 VL - 13 IS - 1 AB - Numerous studies on publication bias in clinical drug research have been undertaken, particularly on the association between sponsorship and favourable outcomes. However, no standardized methodology for the classification of outcomes and sponsorship has been described. Dissimilarities and ambiguities in this assessment impede the ability to compare and summarize results of studies on publication bias. To guide authors undertaking such studies, this paper provides recommendations for a uniform assessment of publication bias related to funding source.
