Figure 2. — Funnel plots showing (A) the tubular adenoma diagnostic rate data in the first year of the study, (B) the sessile serrated adenoma diagnostic rate data in the first year of the study, (C) the tubular adenoma diagnostic rate data in the second year of the study, and (D) the sessile serrated adenoma diagnostic data in the second year of the study. The horizontal line in the center of the funnel is the group median diagnostic rate. The dashed (inner funnel) curves represent the boundaries of the 95% CI and correspond to P < .05. The solid (outer funnel) curves represent the boundaries of the 99.9% CI and correspond to P < .001. CI indicates confidence interval.
