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
introductionAnti-integrin αvβ6 (anti-αvβ6) autoantibodies serve as a diagnostic biomarker and are associated with poor prognosis in ulcerative colitis (UC). We aimed to investigate whether anti-αvβ6 autoantibody levels predict treatment outcomes of advanced therapies in patients with moderately to severely active UC.
methodsAnti-αvβ6 autoantibody levels were measured using prospectively collected serum samples at the initiation of advanced therapies. The primary outcome was treatment persistence up to 1 year; secondary outcomes included clinical remission rates at weeks 2, 6, 14, 24, and 48, comparing low-level and high-level groups stratified by an optimal cutoff from receiver operating characteristic analysis.
resultsA total of 144 patients were analyzed (121 [84.0%] with extensive colitis and 87 [60.4%] with prior exposure to advanced therapies). The median observation period was 10 months, and treatment discontinuation occurred in 70 patients (48.6%). Treatment persistence was significantly higher in the low-level group (log-rank test, P = 0.002), and multivariable Cox analysis identified low antibody levels as the only independent predictor (hazard ratio, 1.90; 95% CI, 1.09-3.32). Clinical remission rates were consistently higher in the low-level group throughout all time points, with the greatest difference at week 6 (47.5% vs 20.0%; χ 2 test, P = 0.003). Low antibody levels remained an independent predictor of remission at all time points. DISCUSSION: Anti-αvβ6 autoantibodies predicted both treatment persistence and clinical remission after advanced therapies, highlighting their potential as a predictive biomarker in patients with active UC.
