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: Metabolic syndrome represents a cluster of interrelated cardiometabolic abnormalities associated with coronary artery disease. However, conventional definitions evaluate metabolic syndrome categorically and may not adequately reflect its cumulative severity. The primary objective of this study was to assess whether the metabolic syndrome severity Z-score (MetS-Sz) was independently associated with coronary artery disease complexity, as quantified by the SYNTAX score, in patients with chronic coronary syndrome. Methods: This single-center retrospective cross-sectional study included 156 patients with chronic coronary syndrome who underwent coronary angiography. MetS-Sz was calculated using age-, sex-, race-, and body mass index-based metabolic variables, whereas coronary lesion complexity was assessed using the SYNTAX score. Participants were categorized into lower (MetS-Sz < 0) and higher (MetS-Sz ≥ 0) MetS-Sz groups, corresponding to values below and at or above the reference population mean. Clinical, anthropometric, and biochemical characteristics were compared between groups. Correlation analysis and multiple linear regression were performed to evaluate the association between MetS-Sz and the SYNTAX score. Results: Of the 156 participants, 123 (78.8%) were men and 33 (21.2%) were women. Patients in the higher MetS-Sz group had significantly higher body mass index, triglyceride, total cholesterol, low-density lipoprotein cholesterol, glucose, diastolic blood pressure, and SYNTAX scores and lower high-density lipoprotein cholesterol levels than those in the lower MetS-Sz group (all Conclusions: Higher MetS-Sz was independently associated with greater coronary artery disease complexity in patients with chronic coronary syndrome. These findings suggest that assessment of cumulative metabolic burden using MetS-Sz may complement conventional cardiovascular risk evaluation. Prospective, multicenter studies are required to confirm its potential role in coronary risk stratification.
