Comparison of anti-rGAPDH IgG and anti-rGAPDH IgM levels in the normal, CIN I, CIN II, CIN III and cervical cancer groups in ELISAs using rGAPDH as the coating antigen. (A) Levels of anti-rGAPDH IgG. (B) Levels of anti-rGAPDH IgM. The central lines represent the mean values, and the error bars indicate the ranges of the standard error of the mean. Total, n=129; normal, n=29; CIN I, n=17; CIN II, n=23; CIN III, n=30; and cervical cancer, n=30. Statistical analysis was performed using the Kruskal-Wallis test with Dunn's multiple comparison test. *P<0.05, **P<0.01 and ***P<0.001, as indicated. rGAPDH, recombinant GAPDH; CIN, cervical intraepithelial neoplasia; IgG/IgM, immunoglobulin G/M.
