Pulmonary hypertension parameters in relationship with OSA severity.

Echocardiographic variables		AHI <5 events·h^−1	Mild OSA	Moderate OSA	Severe OSA
PASP (mmHg)	Guvenc et al. [31]	30.94 ± 6.47		38.35 ± 8.6		0.002
	Zhou et al. [15]	16.7 ± 6.2	18.2 ± 6.6	31.2 ± 5.6^†	32.8 ± 6.7^†	<0.05
PAT (ms)	Shivalkar et al. [34]	22 ± 8	32 ± 10			0.004
	Guvenc et al. [31]	118.36 ± 16.36		103.13 ± 18.42		0.001

PASP: pulmonary artery systolic pressure; PAT: pulmonary artery acceleration time; AHI: apnea-hypopnea index; OSA: obstructive sleep apnea. ^†Significantly different from AHI <5 events·h⁻¹.
