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
backgroundCrohn's disease (CD) is a debilitating gastrointestinal disease with complex etiology. Although effective, recipients of anti-tumor necrosis factor (TNF) agents may experience primary or secondary nonresponse, necessitating alternative treatments. This study is intended to compare the short-term effectiveness of ustekinumab and vedolizumab in treating CD after failure of multiple lines of anti-TNF therapy using real-world data.
methodsA retrospective study was conducted at a tertiary hospital in Dammam, Saudi Arabia, including adults (≥18 years old) with CD who did not respond to anti-TNF therapy. Primary endpoints were clinical improvement per the Harvey-Bradshaw Index (HBI) scores and remission at 12 weeks on an ordinal outcome scale. Secondary endpoints included clinical, biochemical, and endoscopic remission; clinical response; corticosteroid-free days; and cumulative steroid dose. Proportional odds and logistic regression Bayesian models were used to analyze outcomes, and the probability of treatment effectiveness was calculated from the posterior distribution.
resultsThe study included 101 patients (ustekinumab, n = 71 and vedolizumab, n = 30) with a median age of 32 years (IQR: 26.0-38.0); 54.4% were male. At 12 weeks, the HBI endpoint showed an adjusted odds ratio (aOR) = 0.60 (95% confidence interval [CI]: 0.25-1.31), favoring ustekinumab, with a 75% probability of treatment effectiveness over vedolizumab. The clinical ordinal scale had an aOR = 0.61 (95% CI: 0.26-1.35) with a 73% probability of effectiveness for ustekinumab. Ustekinumab was also associated with favorable outcomes in secondary endpoints, reaching up to a 90% probability of effectiveness.
conclusionIn CD patients with anti-TNF failure, ustekinumab was more effective than vedolizumab in the short term. These real-world insights contribute to understanding CD management but require validation in larger prospective studies and randomized controlled trials.
