¹P values indicate pairwise comparisons using the Bonferroni correction.

²For white blood cell count, Cox proportional hazards regression was performed using values scaled per 100/μL increase.

Categorical variables are expressed as n (%). Hazard ratios and P values were estimated using Cox proportional hazards regression analysis. 5-ASA: 5-aminosalicylic acid; BMI: Body mass index; WBC: White blood cell count; ESR: Erythrocyte sedimentation rate; CRP: C-reactive protein; PRO-2: 2-item patient-reported outcome; MES: Mayo endoscopic subscore; HR: Hazard ratio; Ref: Reference; TC: Total cholesterol.
