However, the segmental pattern of healing in UC remains unclear. Endoscopic improvement (EI), a key therapeutic endpoint, is typically assessed using the Mayo endoscopic score (MES), which scores the worst affected area and may miss partial/segmental healing. This study evaluates healing patterns in UC and compares conventional MES with a 3-segment MES approach for detecting treatment effects in clinical trials.  \nMethods: A post hoc analysis of HIBISCUS I/II and GARDENIA trials was conducted in UC patients with moderate-to-severe disease (MES >2 up to the descending colon) . The primary outcome was the proportion of anti-tumor necrosis factor–treated participants achieving MES ≤1 in the descending colon, sigmoid colon, and rectum at week 10. Secondary outcomes included conventionally measured EI, segmental MES improvements, clinical response, and Patient-Reported Outcome 2 (PRO2) normalization. Outcomes were compared between adalimumab, infliximab, and placebo groups.  \nResults: Among 300 participants, 217 received infliximab or adalimumab, while 83 received placebo. Healing followed a proximal-to-distal pattern, with the highest EI in the descending colon and the lowest in the rectum. Infliximab-treated patients continued this trend at week 54. Anti-tumor necrosis factor therapy significantly improved EI vs placebo (42 .9% vs 19.3%; P\u003C .001) . No segmental MES approach outperformed conventional MES for detecting treatment effects. Combined endpoints (MES ≤1 + PRO2 normalization) better captured therapeutic benefits than PRO2 alone (28 .6% vs 13.3%; P = .006) .  \nConclusions: UC healing follows a proximal-to-distal pattern. Conventional MES remains superior for detecting treatment effects over segmental MES. Further studies should explore alternative endoscopic scoring methodologies.  \nKey words: ulcerative colitis, Mayo endoscopic score, endoscopic improvement  \nLay Summary  \nAnti-tumor necrosis factor therapies in moderate-to-severe ulcerative colitis promote a proximal-to-distal healing pattern. The conventional Mayo endoscopic score best detects treatment effects over segmental scoring. Combining the Mayo endoscopic score with clinical symptom scores enhances therapeutic benefit assessment in clinical trials.  \nReceived for publication: May 20, 2025.
