Relationship of recreational physical activity to total fecal bile acid concentration by triglyceride status^* (N = 710)

Level of triglycerides†	Daily recreational physical activity	β coefficient‡	95% CI	Predicted total fecal bile acids (μg/mL)§
< 136 mg/dL	< 15 min	ref.	-	283
	15 to < 45 min	- 0.310	- 0.574 to - 0.046	208
	45 to < 105 min	- 0.275	- 0.530 to - 0.019	215
	≥ 105 min	- 0.419	- 0.683 to - 0.155	186
≥ 136 mg/dL	< 15 min	- 0.007	- 0.262 to 0.249	281
	15 to < 45 min	- 0.083	- 0.346 to 0.180	261
	45 to < 105 min	- 0.026	- 0.296 to 0.243	276
	≥ 105 min	- 0.040	- 0.231 to 0.310	295

^*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 < 136 mg/dL and physical activity < 15 min/day

^§Calculated for females at median age (68.3 years), dietary fiber (19.3 g), and BMI (26.6 kg/m²)
