Body fat mass percentage and appendicular lean mass (ALM) were assessed using dual\u2010energy x\u2010ray absorptiometry. Participants were categorized into four body composition profiles: high body fat (n\u00a0=\u00a086), low lean mass (n\u00a0=\u00a011), combined (n\u00a0=\u00a08), or neither (n\u00a0=\u00a055). Pain and patient\u2010reported physical function were assessed using the Numeric Rating Scale and the Western Ontario and McMaster Universities OA Index, respectively. Associations between body composition measures and symptom outcomes were examined using linear regression, and differences across body composition profiles were analyzed using one\u2010way analysis of variance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Neither body fat mass percentage nor ALM was significantly associated with pain or patient\u2010reported physical function.
