Association between physical activity and PD incidence in the Vasaloppet cohort, based on participation in a long-distance ski race (skiers) compared to non-skiers. Cox regression models showing hazard ratio (HR) with 95% confidence interval (CI) for risk of PD. Adjusted model for age, sex, and education.
