Relationship between impact factor and the level of non-citation within a journal The proportion of articles which have not been cited is compared with impact factor (log scale) for immunology (a) and surgical (b) journals. There were significant correlations. For immunology journals (n = 105), Spearman Rank correlation rho = -0.854 p < 0.0001. For surgial journals (n = 120), Spearman Rank correlation rho = -0.924 p < 0.0001.
