Correlations between respiratory parameters and RSA metrics

Respiration Rate Tidal Volume ln(Tidal volume)1
RSAP-B −0.30* (−.30) 0.17 (.17) 0.19 (.19)
P2T (ms) −0.40* (−.40) 0.34* (.33) 0.34* (.33)
HF −0.23 (−.24) 0.19 (.20) 0.20 (.21)

Correlations between the RSA metrics and the natural logarithm of tidal volume were calculated, since the kurtosis of tidal volume violated the assumption of normality.
