Cox proportional hazards model. HRs reflect the risk associated with a 1-unit increase. A two-sided P value < 0.05 was considered statistically significant. Age at onset refers to the age at onset of stricture-related symptoms. CD: Crohn’s disease; NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio; CLR: C-reactive protein-to-lymphocyte ratio; ESR: Erythrocyte sedimentation rate.
