Estimated regression coefficients for the extended model adjusted for possible confounding variables

	Estimate	95% HPD CI	p value
Intercept	0.176	−2.01; 2.30	0.950
Sex (male vs. female)	0.039	−0.01; 0.09	0.117
Age (per 10 years)	0.016	−0.00; 0.03	0.065
Weight (per 10 kg)	−0.037	−0.19; 0.10	0.550
Height (per 10 cm)	0.023	−0.10; 0.16	0.648
BMI (per 10 units)	−0.026	−0.41; 0.40	0.967
Incontinence (yes vs. no)	0.003	−0.05; 0.06	0.903
Sport (yes vs. no)	0.015	−0.03; 0.05	0.495
Group (cLBP vs. control)	−0.030	−0.07; −0.01	0.098

The estimates show how much the log(TrA ratio) is expected to change if a factor is increased by 1 unit. Example: an increase in weight of 10 kg corresponds to a decrease in the log(TrA ratio) of −0.037
