Figure 1 Prevalence rates of proximal serrated lesions in 31 centers. The vertical axis (P) is the fraction of patients with 1 or more proximal serrated lesions. The average detection rate of 2.8% is designated by the hashed line. Numbers on the horizontal axis represent 31 centers ordered by decreasing numbers of colonoscopies from left to right. Four centers with no detection are not depicted. Circles represent individual center detection rates, and bars designate 95% confidence intervals. Asterisks designate centers with detection rates significantly above or below the average detection rate for all centers.
