*All analyses are bivariate.
†Multivariate analysis of all variables below and n = 136 in all analyses including ongoing physical activity due to 8 participants without acceleration data (see “Ongoing physical activity during HRV recording” section).
BF indicates Bayes factor; logHF, logarithmic high frequency.
