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
Purpose: The impact of hepatic steatosis severity on postoperative weight loss outcomes remains unclear. This study aimed to evaluate the effect of fatty liver severity on percentage of excess weight loss (%EWL) in patients undergoing laparoscopic sleeve gastrectomy (LSG). Methods: This retrospective cohort study included 226 patients with obesity who underwent LSG. Baseline data included liver biopsy grade (mild, moderate, or severe), body mass index (BMI), liver function, and metabolic parameters. Postoperative outcomes were assessed at 1, 3, 6, and 12 months. Statistical methods included the Pearson and Spearman correlations, chi-square test, Kruskal-Wallis test, general linear models, Kaplan-Meier analysis, and multivariate regression to identify the predictors of weight loss and cumulative rates of achieving 50% EWL and to plot the cumulative incidence curve. Results: Baseline BMI, homeostasis model assessment for insulin resistance, free fatty acids, and A1C levels were significantly associated with steatosis severity (P < 0.05). Severe metabolic dysfunction-associated steatotic liver disease (MASLD) was associated with a lower %EWL at 1, 3, 6, and 12 months (1 month %EWL: 32.34% vs 38.59% in the mild group; P < 0.05). The Kaplan-Meier analysis showed delayed achievement of 50% EWL in the severe group (P < 0.05). Multivariate regression analysis identified MASLD severity and preoperative BMI as independent predictors of %EWL. General linear models confirmed the significant dynamic effects of MASLD severity on weight loss over time (P < 0.05). Conclusion: MASLD severity significantly affects postoperative weight loss and delays the achievement of optimal outcomes, especially in the early postoperative period. Preoperative evaluation of liver pathology is essential for optimizing surgical outcomes in patients with obese having MASLD.
