Table 2 Factors associated with compliance with CPAP therapy beyond one year in Pakistani patients on univariate analysis

Factors	Compliant	Non-Compliant	p-value
Factors	(n = 46)	(n = 29)	p-value
Affecting increasing compliance with
CPAP therapy
BMI (kg/m²)	38.2 ± 11.9	31.7 ± 6.5	0.015
ESS score before CPAP	17.5 ± 4.1	12.6 ± 6.7	0.005
Witnessed apnea before CPAP	33 (72%)	7 (30%)	0.001
Improved daytime activity with CPAP	43 (94%)	11 (73%)	0.05
ESS score improved with CPAP	43 (94%)	11 (73%)	0.05
