The IPTW-adjusted proportion of patients with an infusion reaction through week 52 (a); the IPTW-adjusted proportion of patients with an infusion reaction at each infusion (b); and CDAI and IPTW-adjusted mean change in CDAI score among biologic-naïve patients at month 6 and month 12 (c). In panel c, the mean change from baseline in CDAI is based on ANCOVA after adjusting for both baseline CDAI and IPTW propensity score.
