Figure 1. Love plot for absolute standardized differences.

Love plot displaying absolute standardized differences comparing 116* baseline characteristics between older HF-PEF patients receiving new discharge prescriptions for aldosterone antagonists and not receiving any aldosterone antagonists, before and after propensity score matching. (Hx=past medical history, A=admission, D=discharge, H=in-hospital, PF=precipitating factor, ACE=angiotensin-converting enzyme, ICD=Implantable cardioverter-defibrillator, ARB=angiotensin receptor blocker, CABG=coronary artery bypass grafting, CCB=calcium channel blocker, COPD=chronic obstructive pulmonary disease, JVP=jugular venous pressure, PCI=percutaneous coronary intervention, PND=paroxysmal nocturnal dyspnea, TIA=transient ischemic attack; *4 regions entered as a single categorical variable in the model, dialysis during hospitalization was in the model but excluded from figure as there was no cases in the matched data)
