  • NOTE: Total fecal bile acid concentration, dietary fiber, and BMI are natural log-transformed.

    Abbreviation: CI, confidence interval.

  • * Calculated for females at median age (68.3 y), dietary fiber (19.4 grams), and BMI (26.6 kg/m2).

  • Adjusted for age and sex.

  • Adjusted for all confounders (change β coefficient > 10%): age, sex, dietary fiber, and BMI.
