Factors associated with resting HRV indices among all participants

^*p<0.05, ^**p<0.01, ^***p<0.001, ^†point-biserial correlations; first category in parenthesis is the reference group, ^‡product-moment correlations. BMI: body mass index, Var: total variance [ln (ms²)], LF: low frequency power [ln (ms²)], HF: high frequency power [ln (ms²)], LF/HF: ratio of LF to HF [ln (ratio)], HRV: heart rate variability
