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
This cohort study aims to evaluate the capability of non-invasive left ventricular pressure-strain loop (LV-PSL) analysis using myocardial work parameters to predict coronary artery occlusion in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). A total of 113 patients suspected of having NSTE-ACS underwent PSL analysis prior to coronary angiography to obtain myocardial work parameters such as global work index (GWI), global constructive work (GCW), global wasted work (GWW), and work efficiency (GWE). Based on the results of coronary angiography, patients were categorized into two groups: non-occluded (65 cases) and occluded (26 cases). The study compared differences in left ventricular global longitudinal strain (GLS) and myocardial work parameters between the groups and assessed the predictive value of these parameters for diagnosing coronary artery occlusion. The occluded group exhibited significantly higher GWI, GCW, and GWE values and lower GLS and GWW values (P < 0.05). The area under the curve (AUC) for detecting coronary occlusion was superior for GWI compared to GLS, GCW, GWW, and GWE. Additionally, combining GLS with myocardial work parameters improved diagnostic efficacy (P = 0.016). GWI-focused LV-PSL analysis more effectively detects coronary occlusion in NSTE-ACS, guiding early intervention and improving diagnostic accuracy.
