Table 4 Spearman correlation coefficient between respiratory reactance at 5 Hz (Xrs5) and Zrs5, R0, and R5 for male and female subjects

From: Impact of obstructive sleep apnea on lung volumes and mechanical properties of the respiratory system in overweight and obese individuals

Parameter Male (n = 180) p Female (n = 70) p

Respiratory impedance at 5 Hz (Zrs5) −0.638 <0.001 −0.725 <0.001
Respiratory resistance at 0 Hz (R0) −0.590 <0.001 −0.644 <0.001
Respiratory resistance at 5 Hz (R5) −0.577 <0.001 −0.637 <0.001
