Figure 1: A frequency histogram of wait-time in days from receipt of referral to endoscopy in all included subjects () is shown in the figure. Wait-times are shown in 30-day intervals with the exception of the last bar (241–450 days). The 60-day benchmark appears as a vertical line at the 60-day mark. 102 of 246 subjects (41%) had their first endoscopic procedure within 60 days; wait-times ranged from 1 to 428 days.
