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: Acute myocardial infarction is a leading cause of death worldwide. ST-segment elevated myocardial infarction patients exhibit different plaque morphology depending on many factors. However, the development of pathological states should not be attributed to a single factor alone. Therefore, a new formula is needed to comprehensively predict plaque characteristics to improve patient risk stratification and enable precision management. Methods: This study include patients first diagnosed ST-segment elevation myocardial infarction who underwent optical coherence tomography before the intervention. NGSA2/P2 = ln ((non-high-density lipoprotein cholesterol / high-density lipoprotein cholesterol)*Glycosylated hemoglobin * admission systolic blood pressure * (Age) Results: A total of 268 patients were analyzed. Compared to the plaque erosion patients, the plaque rupture patients were older, had lower platelet counts, a higher prevalence of multi-vessel disease, and significantly higher levels of NGSA2/P2. Plaque rupture was positively correlated with age and NGSA2/P2 values, and negatively correlated with platelet counts. Compared to T0 group, the T1 and T2 groups had more cholesterol crystals, macrophages, thin-cap fibroatheromas, smaller normal°, greater lipid-rich° and lipid core index. Conclusions: The new formula NGSA2/P2 integrates multiple indicators and provides superior predictions of plaque characters compared to the observation single factor. For older patients, it may be particularly important to strengthen the regulation of lipids, blood pressure, blood glucose, and platelet counts.
