Sleep duration modifies the association between obstructive sleep apnea risk and glaucoma: evidence from the Korea National Health and Nutrition Examination Survey

Table 4 Effects of the interaction between a sleep duration (< 9 h) and OSA risk on glaucoma prevalence

Sleep duration (< 9 h)	Unadjusted		Model 2		Model 3		Model 4
Sleep duration (< 9 h)	OR (95% Cl)	P value	aOR (95% Cl)	P value	aOR (95% Cl)	P value	aOR (95% Cl)	P value
Overall week	2.34 (0.92–5.94)	0.074	2.78 (1.10–7.00)	0.031	2.80 (1.11–7.07)	0.030	2.72 (1.07–6.92)	0.035
Weekday	2.50 (0.95–6.61)	0.064	2.94 (1.11–7.68)	0.030	2.94 (1.12–7.73)	0.029	2.93 (1.11–7.74)	0.031
Weekend	1.47 (0.74–2.93)	0.275	1.58 (0.79–3.18)	0.194	1.59 (0.80–3.20)	0.187	1.76 (0.88–3.52)	0.111

OR = odds ratio; aOR = adjusted odds ratio; CI = confidence interval; OSA = obstructive sleep apnea
Logistic regression models included interaction terms for sleep duration and OSA risk. Adjustments were applied as outlined in the model specifications
Model 2: Adjusted for gender and age
Model 3: Adjusted for variables in Model 2, with additional adjustments for smoking, drinking, physical activity, educational level, and income level
Model 4: Adjusted for variables in Model 3, with additional adjustments for intraocular pressure, metabolic syndrome, stress level, and refractive error
