Frailty was assessed using the Clinical Frailty Scale (\u22654; 63%), and complementary analyses were performed using frailty\u2010related factors (low body mass index, reduced activities of daily living, malnutrition, and dementia). The primary outcome was a composite of cardiac death or HF rehospitalization within 1\u2009year, which occurred in 766 patients (18%). A propensity score was calculated using variables associated with SGLT2i prescription.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      After propensity score\u2013based inverse probability of treatment weighting adjustment, SGLT2i use was associated with a lower risk of the primary outcome (hazard ratio [HR], 0.76,\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.045).
