Vedolizumab and Adalimumab in Biologic-Naïve Ulcerative Colitis: Comparison of Patient-Level Clinical Trial Data and VARSITY for Week 6 Clinical Remission.
Article in Digestive diseases and sciences, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIndirect treatment comparisons using patient-level data are increasing in popularity within inflammatory bowel disease research. We compared the efficacy of adalimumab and vedolizumab for biologic-naïve moderate-severe ulcerative colitis (UC) using indirect comparisons of phase 3 clinical trials and compared the results to the RCT VARSITY.
designPooled analysis of patient-level data from 518 biologic-naïve patients with UC was performed using GEMINI-1 and ULTRA-1. Proportions of patients achieving week 6 clinical remission and clinical response were compared, and propensity score matching and multivariate logistic regression were used to account for potential confounders. These results were compared to those derived from VARSITY.
resultsA numerically greater proportion of vedolizumab-treated patients from GEMINI-1 achieved week 6 clinical remission compared to those treated with adalimumab [136/388 (35.1%) vs. 38/130 (29.2%)]. Similar findings were observed among the propensity score matched cohort [33/110 (30.0%) vs. 25/110 (22.7%), adjusted OR (aOR) 1.56 (95% confidence interval (CI) 0.81-3.02), p = 0.187]. A similar magnitude for absolute difference in the proportions of patients achieving week 6 clinical remission was observed from VARSITY in vedolizumab compared to adalimumab [131/305 (43.0%) vs. 114/307 (37.1%), OR 1.27 (95% CI 0.92-1.76), p = 0.142].
conclusionsIn this post hoc analysis, a similar magnitude in the absolute difference of efficacy at week 6 among biologic-naïve patients was observed using indirect comparisons of phase 3 clinical trial data as was observed in VARSITY. Indirect comparisons using patient-level clinical trial data could be used to inform drug choices for future head-to-head trials and guide positioning of drugs in the absence of head-to-head trials.
