Associations of physical activity measures (minutes/day) with node degree. Regression coefficients and 95% CI indicate the mean difference in node degree per SD higher PA or lower sedentary time. Model 1, adjusted for age, sex, education level, MRI lag time, and wake time. Model 2, additionally adjusted for diabetes status. Model 3, additionally adjusted for BMI, systolic blood pressure, antihypertensive medication, total-to-HDL-cholesterol ratio, lipid-modifying medication, smoking status, alcohol use, and history of cardiovascular disease
