Variable	Univariate OR (CI 95%)	p	Multivariate OR (CI 95%)	p
Severe disease	0.47 (0.17–1.21)	0.116
Perianal disease (EC)	0.214 (0.044–1.038)	0.056
Fecal calprotectin (UC)	14.2 (1.59–127)	0.017
Referral during admission	2.3 (1.03–7.09)	0.042	2.78 (1.032–7.501)	0.043

Hosmer and Lemeshow test: p = 0.421; Cox–Snell R²: 0.104. Nagelkerke R²: 0.155; Sensitivity: 13 (2.5–25); Specificity 96 (92–98); PPV: 55 (23–88); NPV: 77 (69–84). This table only shows the results of the univariate analysis of the variables that were finally included in the multivariate analysis. The model displayed here is significant, explains between 0.104 and 0.155 of the dependent variable, and correctly classifies 75.7% of cases. IBD, inflammatory bowel disease; MODs, missed opportunities for diagnosis.
