Table 3. Odds of post-colonoscopy complications during early (July to September) vs. later (April to June) academic months.

Complications	Adjusted OR	95% CI (UL–LL)	P value
Colon perforation	0.99	0.93–1.06	0.760
Postoperative bleeding/hematoma	0.92	0.81–1.04	0.196
Postoperative infection	0.99	0.84–1.15	0.850

P<0.05 indicate clinical significance. A multivariate regression model was controlled for age, sex, race, median household income and payer status. OR, odds ratio; CI, confidence interval; LL, lower level; UL, upper level.
