Computed Tomography Findings as a Novel Predictor of Alcohol-Associated Hepatitis Outcomes.
Article in Digestive diseases and sciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAccurate prediction of outcomes for alcohol-associated hepatitis (AH) is critical, as prognosis determines treatment eligibility. Computed tomography (CT) features may provide prognostic information beyond traditional models.
aimsOur aim was to identify CT features that predict outcomes in AH.
methodsWe studied 108 patients retrospectively with definite or probable AH, who underwent admission abdominal CT. A radiologist blinded to outcome evaluated eight CT features. The primary outcome was 90-day mortality.
resultsTwenty-five (23.2%) patients died within 90 days. While traditional prognostic tools, including Maddrey discriminant function (DF), predicted 90-day mortality (OR 1.01 [1.00, 1.03], P = 0.02), abdominal CT findings were also accurate predictors. On abdominal CT, patients with severe AH had larger volume of ascites (moderate/large volume: 34.0 vs. 8.2%, P < 0.0001), longer liver length (17.1 vs. 15.1 cm, P = 0.001), greater liver heterogeneity (moderate/severe: 21.3 vs. 8.2%, P = 0.007), and more likely to have splenomegaly (42.6 vs. 18.0%, P = 0.009) than those with mild AH. Univariate analysis revealed that ascites volume (OR 2.59 [1.35, 4.96], P = 0.004) predicted 90-day mortality. In multivariate analysis, degree of ascites predicted 90-day mortality when controlling for Maddrey DF (OR 2.36 [1.19, 4.69], P = 0.01) and trended toward significance when controlling for MELD score (OR 2.02 [0.95, 4.30], P = 0.07).
conclusionCT findings in AH differentiate disease severity and predict 90-day mortality; therefore, the role of CT warrants further investigation as a tool in AH management.
