The relationship between frailty and outcomes and the role of frailty in modulating the benefits of spironolactone were examined in a subset of 1767 TOPCAT patients. For the cohort as a whole (mean age 71.5\u2009years, 49% female), the mean FI at baseline was 0.37\u2009\u00b1\u20090.11. Four frailty classes were defined ranging from FI &amp;lt;\u20090.3 to FI \u2265\u20090.5. Overall, 94% of subjects were considered frail (defined as a FI &amp;gt;\u20090.21). Mean age was lowest for the most frail class (69\u2009\u00b1\u20099\u2009years for Class 4; 73\u2009\u00b1\u200910\u2009years for Class 1; P\u2009&amp;lt;\u20090.001). Body mass index, systolic blood pressure, and pulse pressure all increased as FI increased. Both primary and secondary outcomes increased as frailty severity increased. There was no interaction between frailty class and treatment effect of spironolactone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Frailty was very common in TOPCAT HFpEF participants.
