Body mass index, exercise capacity and functional status in chronic heart failure.
Article in BMC cardiovascular disorders, 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
aimsThis short communication aims to assess the associations of body mass index (BMI) with key functional parameters, including exercise tolerance and functional status, among individuals with chronic heart failure. METHODS AND
resultsFrom four chronic heart failure studies ( HF-ACTION [Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training], NEAT-HFpEF [Nitrate's Effect on Activity Tolerance in Heart Failure With Preserved Ejection Fraction (HFpEF)], INDIE-HFpEF [Inorganic Nitrite Delivery to Improve Exercise Capacity in HFpEF], and RELAX-HFpEF [Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Heart Failure with Preserved Ejection Fraction]), we studied 2,546 participants (mean age: 60.2 ± 12.8 years, 67.8% men, 43.7% non-Whites individuals, 83% with heart failure with reduced ejection fraction (HFrEF), 17% with heart failure with preserved ejection fraction [HFpEF]). Among them, 52.8% had obesity [n = 1344], 29.8% were overweight [n = 758], and 17.4% had a normal body mass index [n = 444]). One-unit increment in BMI (kg/m
conclusionsOur study found that in patients with chronic heart failure, increasing body mass index is associated with poor exercise capacity and functional status. Our findings underscore the potential importance of optimizing weight management among individuals with chronic heart failure to improve functional status.
