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
Introduction: The obesity paradox has been observed in patients with cardiovascular disease. The goal of this study was to evaluate if obesity has a protective effect in patients presenting with non-ST-elevation myocardial infarction (NSTEMI). Methods: Using a large Nationwide Inpatient Sample (NIS) database, we evaluated mortality in patients with NSTEMI based on weight categories in adults. Results: A total of 3,597,279 NSTEMI patients were found in the database over the age of 18 years. We found that overweight and obesity, followed by morbid obesity, had the lowest mortality using univariate (overweight mortality of 3.2% vs. obesity mortality of 3.78% vs. morbid obesity mortality of 5.69% vs. 7.8% of normal weights), whereas cachexia was associated with the highest mortality in univariate analysis (cachexia 21.82%). Using multivariate analysis adjusting for baseline characteristics and comorbidities, those relations remained unchanged (cachexia Multivariate Odds ratio (MVOR): 2.56, confidence interval [CI]: 2.41-2.73, Conclusion: We observe an obesity paradox in patients with NSTEMI, showing that overweight, followed by obesity and morbid obesity, have the lowest mortality, with cachexia having the highest mortality.
