The time to inflammatory bowel disease (IBD) comparing patients with vs. without a chronic inflammatory skin disease (CISD), after propensity-score decile stratification. Green represents the exposure group and blue represents the referent (non-CISD) group, with the green and blue shaded regions indicating the corresponding 95% confidence intervals. All Kaplan–Meier curves were not extended beyond the time when <10% of patients remain in the risk set, because they become unreliable. The IBD event is defined as inpatient IBD, or outpatient IBD with endoscopic confirmation.
