The association of physical activity level (A) and sedentary leisure time (B) with CIMT^a. ^aβ of physical activity level (per SD increase:β=-0.0103; 95CI: -0.0154, -0.0053) and sedentary leisure time (per SD increase:β=-0.0004; 95CI: -0.0052, 0.0043) with CIMT was estimated by linear regression, adjusted for, if not sedentary leisure time by, sex, age, BMI, WC, SBP, DBP, current smoker, alcohol drinker, education, household income, fasting glucose, TC, HDL-C, TG, LDL-C and sedentary leisure time. The dotted lines represent the 95% confidence intervals for the spline model. The range of physical activity level was restricted to 1.3 to 55.7 MET-h/d because predictions less than 1.3 MET-h/d (1th percentile) and greater than 55.7 MET-h/d (99th percentile) are based on too few data points. The range of sedentary leisure time was restricted to 0.43 to 4.0 h/d because predictions less than 0.43 h/d (5th percentile) and greater than 4.0 h/d (95th percentile) are based on too few data points
