  • NOTE: Model is adjusted for age, sex, dietary fiber, and BMI. Total fecal bile acid concentration, dietary fiber, and BMI are natural log-transformed.

  • * Likelihood–ratio test for interaction between physical activity and triglycerides P = 0.079.

  • All β coefficients are relative to the reference group: triglycerides of <136 mg/dL and physical activity of <15 min/d.

  • Calculated for females at median age (68.3 y), dietary fiber (19.3 grams), and BMI (26.6 kg/m2).
