Table 2.

Exposure effect models constructed with obstructive sleep apnea categories as the exposure, SARS-CoV-2 seropositivity and symptomatology as the outcomes, and confounders as independent variables. The coefficients are the difference between the adjusted proportions.

Exposure	Independent variables	Outcomes	Exposure effect proportion (95% C.I.)a	Exposure effect coefficient (95% C.I.)b	pvalue
OSA categories	Age, gender, obesity, hypertension, diabetes, hypercholesterolemia, individuals per house, and home confinement.	SARS-CoV-2 seropositivity	46.3 (34–58.5)	OSA mild vs none: 0.009 (−0.15 to 0.17)	0.915
				OSA mod-severe vs none: 0.175 (−0.02 to 0.37)	0.084
		SARS-CoV-2 symptomatology	44.2 (31.2 – 57.1)	OSA mild vs none: − 0.032 (−0.20 to 0.14)	0.708
				OSA mod-severe vs none: 0.150 (−0.05 to 0.14)	0.141

^aExposure proportion is the proportion with a positive outcome at the referent obstructive sleep apnea category.

^bExposure effect coefficient is the difference between the referent category and obstructive sleep apnea level.
