The associations between age and 1\u2010year changes in AFEQT\u2010overall summary and subdomain scores with rate or rhythm control strategies were estimated using generalized additive models. To address nonlinear relationships, we developed multivariable linear regression models with age range categories (&lt;65, 65\u201375, and \u226575\u2009years).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Results<\/jats:title>\n            <jats:p xml:lang=\"en\">Among 2786 patients (31.7% women); 946 were &lt;65, 1019 were \u226565 to 75, and 821 were \u226575\u2009years, with rate control pursued in 23.4%, 42.0%, and 66.4%, respectively, and their mean 1\u2010year improvements in the AFEQT overall summary were 11.1 (SD: 16.6), 8.0 (17.0), and 4.7 (18.2), respectively. After multivariable adjustment, older age was independently associated with less AFEQT overall summary improvement, regardless of treatment strategy. Patients aged \u226575\u2009years had a smaller AFEQT overall summary improvements than those aged &lt;65\u2009years (difference between groups \u22123.86 points [\u22125.29 to \u22122.42]), primarily
