Exposure-adjusted incidence rates for each AE were calculated by dividing the number of patients experiencing the event by the total PYs, multiplied by 100. PYs were calculated as the sum of each patient's contribution, calculated from the days of exposure (ie, AE onset date minus the date of first dose plus 1 day). For each AE, the PYs were truncated after a patient experienced the AE and each AE was counted only once per patient. Patients who were randomised to placebo and then rolled over into an open-label study could contribute to events in either the placebo or vedolizumab group depending on when they experienced the AE. PYs were calculated accordingly for placebo or vedolizumab for each AE. When the number of events=0, the 95% CI was calculated based on rule of 3 (ie, (0, 3/total PYs)×100).
