P-value is a comparison of mean (¶ = ANOVA)/ median/percentages († = Kruskal Wallis Test/Chi2 Test) between patients with BMI ≤ 21, 21–25 and BMI >25 kg/m2.

Mean (SD), * = median (interquartile range); ¶ = ANOVA; † = Pearson chi2 test/Kruskal Wallis Test.

Abbreviations: BMI: body mass index, CHF: chronic heart failure, eGFR: estimated glomerular filtration rate, LVEF: left ventricular ejection fraction.
