Bar graphs illustrate adjusted mean changes(Δ)in echocardiographic parameters(Panels A-E)and the proportion of treatment responders(Panel F)
among obese(OB)and non⁃obese(Non⁃OB)patients with heart failure with reduced or mildly reduced ejection fraction(HFrEF/HFmrEF)following
inverse probability of treatment weighting(IPTW)adjustment. Error bars indicate standard deviation(SD)for Panels A-E and 95% confidence intervals

(95% CI)for Panel F. P < 0.05.

are effective sample sizes after IPTW adjustment and therefore may be non⁃integers.

Model specifications:Model 1:adjusted for age and sex;Model 2:Model 1 plus baseline LVEF and left ventricular mass;Model 3:Model 2 plus co⁃
morbidities(hypertension,coronary heart disease,atrial fibrillation,diabetes)and key GDMT medication doses(sacubitril/valsartan and metoprolol suc⁃
cinate doses). β denotes regression coefficient for continuous outcomes;OR represents odds ratio for binary outcomes.
