Chromoendoscopy meta-analysis: correcting subgroup analysis interpretation
Feuerstein et al1 conclude that chromoendoscopy is superior to standard-definition white-light endoscopy (SDWLE) but not superior to high-definition white-light endoscopy (HDWLE) in patients with inflammatory bowel disease. They base this conclusion on an analysis of 2 subgroups (chromoendoscopy vs SDWLE and ch romoendoscopy vs HDWLE) within their meta-analysis of randomized trials of chromoendoscopy versus white-light endoscopy. However, their interpretation of this subgroup analysis is incorrect.
