The main outcome was any postoperative infection. Then, 90-day cumulative incidences (absolute risk) and adjusted hazard ratios (relative risk) of the outcome were calculated for high versus no\/low glucocorticoid exposure within all appendectomies and within open and laparoscopic subgroups.

The 90-day cumulative incidence for postoperative infection was 5.3% within the no\/low glucocorticoid exposure group and 10.0% within the high glucocorticoid exposure group.
