Multilevel regression models posterior estimations and 90% credible intervals of variation in phase angle by sex, age, group, maturity offset (model 3), and adjusting for body mass (model 4) among adolescents.

	Model 3 (variation by sex, age group and maturity offset)	Model 4 (variation by sex, age group and maturity offset, adjusted for body mass)
Population-level effects (90% credible interval)
Intercept	0.06 (−1.08 to 1.21)	0.01 (−1.04 to 1.05)
Maturity offset	0.22 (−0.46 to 0.82)	−0.06 (−0.20 to 0.08)
Body mass	-	0.37 (0.28 to 0.45)
Group level estimates (90% credible interval)
Level 2, standard deviation
Age group	0.21 (0.01 to 0.72)	0.49 (0.09 to 0.1.25)
Sex
Intercept	0.90 (0.33 to 1.83)	0.59 (0.09 to 1.51)
Maturity offset (varying slope)	0.42 (0.03 to 1.33)	-
Level 1 standard deviation	0.92 (0.87 to 0.97)	0.88 (0.84 to 0.93)

All outcomes were standardized in the models.
