Effects of body mass index on left ventricular function: An echocardiographic comparison between obese and nonobese individuals.
Article in Physiological reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Obesity is linked to structural and functional cardiac changes. This study assessed the impact of body mass index (BMI) on left ventricular (LV) function. A cross-sectional study included 100 adults (50 obese and 50 nonobese), matched for age and sex. Echocardiographic parameters, end-diastolic volume (EDV), end-systolic volume (ESV), ejection fraction (EF), E/A, E/e ratios, Interventricular Septal thickness in Diastole (IVSd), stroke volume (SV), and cardiac output (CO), were measured by a blinded cardiologist using American Society of Echocardiography (guidelines. Spearman's correlation and multivariable regression evaluated associations between BMI and LV parameters. Obese participants had higher EDV (100.0 ± 23.3 vs. 84.6 ± 25.8 mL), ESV (35.6 ± 10.0 vs. 30.4 ± 12.5 mL), IVSd (9.33 ± 1.53 vs. 8.37 ± 0.91 mm), and SV (67.7 ± 15.2 vs. 57.8 ± 13.9 mL) than nonobese participants (all p < 0.05). EF and E/A ratio were similar. BMI correlated positively with EDV and ESV, negatively with E/A ratio, and independently predicted higher EDV and ESV. Obesity is associated with increased LV volumes, septal thickness, and diastolic dysfunction while preserving systolic function, highlighting the importance of early cardiac evaluation in obese adults.
