	aOR (95% CI)	P value
Anastomosis (reference: end-to-end)	—	—
End-to-side	1.30 (0.69–2.44)	0.41
Side-to-side	0.75 (0.43–1.31)	0.32
Age at CD diagnosis (yr)	0.98 (0.96–1.0)	0.07
CD location (isolated ilealdisease)	0.64 (0.39–1.03)	0.07
Stricturing CD behavior	1.81 (0.89–3.65)	0.10
Postoperative biologic prophylaxis	0.68 (0.36–1.31)	0.25
≥2 ICR (including index ICR)	1.51 (0.97–2.36)	0.07

aHR, adjusted hazard ratio; CD, Crohn's disease; CI, confidence interval; ICR, ileocolonic resection.
