| Predictors | R2 | ΔR2 | β |
| Step 1 | 0.01 | 0.01 | |
| Age (years) | -0.08 | ||
| Body mass index (kg/m2) | 0.67 | ||

| Respiratory activity (Log-pHF-HRV, Hz) | 0.01 | ||
| Step 2 | 0.07 | 0.06∗ | |
| Age (years) | -0.09 | ||
| Body mass index (kg/m2) | 0.11 | ||
| Physical activity (h/w) | -0.06 | ||
| Respiratory activity (Log-pHF-HRV, Hz) | -0.05 | ||

Log-pHF-HRV = log-transformed peak of high frequency heart rate variability, Log-HF-HRV = log transformed high frequency heart rate variability, EQ-15 = Empathy Quotient 15 (Allison et al., 2011).
