Two independent reviewers screened the search results and extracted the data. Effect sizes were calculated as the standardized mean difference (SMDs) with 95% confidence intervals (CIs) using random-effects models. Methodological quality was assessed using the Cochrane Collaboration Risk of Bias Tool 2.0, and the certainty of evidence was evaluated with the GRADEpro online tool. Sensitivity, subgroup, and regression analyses were performed to explore potential sources of heterogeneity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This analysis included six studies with a total of 277 participants with SjD. Compared to controls, physical activity interventions significantly improved cardiopulmonary function (SMD 0.59 [95% CI 0.20 to 0.99]), functional capacity (SMD 0.69 [95% CI 0.33 to 1.05]), general health status (SMD 0.46 [95% CI 0.15 to 0.76]), vitality (SMD 0.51 [95% CI 0.15 to 0.86]), and mental health (SMD 0.42 [95% CI 0.13 to 0.72]).
