(A) Kaplan–Meier estimate of the proportion of patients free of colectomy through 54 weeks for the placebo and combined infliximab groups in ACT-1 and -2. (B) Summary of hazard ratios by subgroup for time to colectomy through 54 weeks after the first infusion in ACT-1 and -2. The vertical solid line represents the treatment effect for the overall population. CI, confidence interval; NAP, not applicable; UC, ulcerative colitis; 5-ASA, 5-aminosalicylates; 6-MP, 6-mercaptopurine. (C) Summary of hazard ratios by treatment group and by study for time to colectomy or commercial infliximab use through 54 weeks after the first infusion in ACT-1 and -2.
