Fig. 3 Survival analysis for time to loss of response in patients retreated with placebo (n = 36, dotted line) or infliximab (n = 37, solid line) through 8 weeks after the last infusion of infliximab or placebo. Patients who had a clinical response at any point during the retreatment period were followed up for the duration of response in this analysis. The time axis is the duration of response determined only during the retreatment period. Differences between infliximab retreatment and placebo retreatment for the median time to loss of response had a P value of 0.057.
