Impact of metabolically healthy obesity on post percutaneous coronary intervention outcomes in patients with acute myocardial infarction: A nationwide propensity matched analysis.
Article in Obesity pillars, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Obesity paradox in post-percutaneous coronary intervention (PCI) outcomes among acute myocardial infarction (AMI) patients is a known controversy. However, these studies included patients who had diabetes, hypertension, or hyperlipidemia. We studied relationship between metabolically healthy obesity (MHO-without diabetes, hypertension, or hyperlipidemia) and in-hospital post-PCI outcomes among AMI patients. Methods: We extracted data from National Inpatient Sample 2020 using International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes for admissions of AMI patients who underwent PCI. We then identified patients with diabetes, hypertension, and hyperlipidemia using Elixhauser comorbidity index and Clinical Classifications Software and excluded them. Then, using Elixhauser comorbidity index, we identified patients with and without obesity, defined as Results: Among 25605 metabolically healthy patients who had AMI and underwent PCI, 2825 had obesity, and 22780 didn't. After propensity score matching (PSM) for age and sex, both cohorts had 2795 patients each. There was no statistically significant difference in in-hospital all-cause mortality (adjusted odds ratio [OR] 1.14, 95 % confidence interval [CI] 0.63-2.10, p = 0.661), post-PCI stroke (aOR 1.17, 95 % CI 0.50-2.75, p = 0.714), acute kidney injury (aOR 1.20, 95 % CI 0.84-1.72, p = 0.322), post-PCI bleeding (aOR 1.04, 95 % CI 0.35 to 3.12, p = 0.940) and intra or post-PCI cardiac arrest (aOR 1.14, 95 % CI 0.30 to 4.42, p = 0.835) between both cohorts. Conclusions: No statistically significant association was found between obesity and post-PCI outcomes in metabolically healthy patients with AMI. Larger studies are needed to explore the controversial "obesity paradox" in cardiovascular diseases.
