Numbers in bold indicate p<0.05. Δ: change (expressed as relative change compared to baseline and as z-score); Rrs6: respiratory resistance at 6 Hz; AX: area under the reactance curve; B: unstandardised regression coefficient. #: final model (R2=0.208); ¶: final model (R2=0.453); +: final model (R2=0.274).
