Comparison of the Relative Sensitivity of Clinical, Endoscopic, and Histologic Remission for Detection of Treatment Efficacy in Ulcerative Colitis Trials.

This systemic review and quantitative analysis of placebo-controlled ulcerative colitis (UC) induction trials found higher pooled histologic remission rates compared with clinical and endoscopic remission rates at the same timepoint, and no significant differences in pooled relative risks for these outcomes between treatment groups; supporting the concept that histologic remission is not less sensitive than clinical or endoscopic remission.
