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
Background: Stable coronary artery disease (CAD), a common condition in CAD, often requires monitoring and treatment. However, predicting its chronic stenosis progression remains challenging. Peri-coronary fat attenuation index (FAI), a quantitative parameter derived from coronary computed tomography angiography (CCTA), may provide valuable information for predicting the chronic stenosis progression of CAD. By examining the relationship between peri-coronary FAI and chronic stenosis progression in three different coronary arteries, we aimed to address a critical knowledge gap in the field of cardiovascular disease prevention and treatment. Methods: A retrospective analysis of 145 stable CAD patients' CCTA images revealed stenosis degree, plaque properties, and quantitative parameters. Patients were divided into progression and no progression groups at three coronary artery levels. Intergroup comparison, univariate and multivariate logistic regression analyses were applied to identify predictors of stenosis progression in each coronary artery. Additionally, subgroup analyses of FAI based on different study intervals were performed. Results: Stenosis progression was most commonly seen in the left anterior descending artery (LAD), especially in its proximal and middle segments. Peri-coronary FAI was significantly higher in the progression group than it was in the no progression group [-72.2±7.8 Conclusions: Baseline peri-coronary FAI is valuable in predicting chronic coronary stenosis progression that occurs within a short period (within 1 year) in RCA, and, potentially, in LM + CX. Stenosis progression in LAD might be mainly driven by factors other than coronary inflammation.
