^aAge at diagnosis was used as the time scale.

^bCox proportional hazards regression model based on the propensity score for physical activity category.

^cMultivariable adjusted Cox model adjusted for age, sex, number of comorbidities, activities of daily living score, Mini-Mental State Examination score, smoking status, body mass index, dietary fiber intake, total calorie intake, ethnicity, marital status, education, and household income.

^dP values for trend were derived from a model including leisure-time physical activity categories modeled as a continuous variable.
