Comparison of cardiovascular co-morbidities and CPAP use in patients with positional and non-positional mild obstructive sleep apnea

Table 3 Continuous positive airway pressure acceptance and compliance among patients with non-positional and positional obstructive sleep apnea

Outcome	Mild		Moderate		Severe		P-value for comparison among severity levels
	Non-positional	Positional	Non-positional	Positional	Non-positional	Positional
	(n = 18)	(n = 52)	(n = 70)	(n = 29)	(n = 178)	(n = 24)
CPAP acceptance by severity	7 (10.00%)		37 (37.37%)		125 (61.88%)		<0.001*
CPAP acceptance in each group	1 (5.56%)	6 (11.54%)	26 (37.14%)	11 (37.93%)	110 (61.80%)	15 (62.50%)
CPAP compliance¹							0.896
High	1 (100%)	4 (66.67%)	18 (69.23%)	7 (63.64%)	79 (71.81%)	11 (73.33%)
Low	0 (0%)	2 (33.33%)	8 (30.77%)	4 (36.36%)	31 (28.19%)	4 (26.67%)
Follow-up duration, months¹	47.00	15.50 ± 9.57	20.62 ± 15.58	23.09 ± 19.54	22.27 ± 15.58	17.07 ± 14.68	NA

CPAP: continuous positive airway pressure, NA: not available due to only one case in one group.
Results are number (percentage) for categorical variables and mean ± standard deviation for continuous variables. Chi-square test or Fisher’s exact test was implemented for categorical variables.
¹Statistics were derived from CPAP acceptors.
