Maintenance-phase mean infliximab trough concentrations in participants with IBD with sustained histologic remission and participants with evidence of histologic relapse are represented by box and whisker plot (a). Median values (thick horizontal line), 25th and 75th percentile values (box outline), 95% confidence intervals (whiskers); *p < 0.05, **p < 0.01, ***p < 0.001. Receiver operator characteristic analysis for maintenance-phase mean infliximab trough concentrations for participants with and without sustained histologic remission (b).
