Five-Minute Awake Snoring Test for Determining CPAP Pressures (Five-Minute CPAP Test): A Pilot Study

Table 4

Spearman’s rank correlation coefficient based on the Five-Minute CPAP Test Quiet Pressures versus other variables. Statistical significance with 2-tailed . % = percent; AHI = apnea-hypopnea index; APAP-95th = Auto-CPAP devices’ 95th percentile download data; BMI = body mass index (in kilograms per meter2); cwp = centimeters of water pressure; LSAT = lowest oxygen saturation; ODI = oxygen desaturation index; = value; = Spearman’s rank correlation coefficient; titration snoring = snoring detected during the polysomnogram; and y = years.
