From: Self-reported snoring is associated with nonalcoholic fatty liver disease
Stratified relative risk (RR) (95% confidence interval (CI)) of snoring on nonalcoholic fatty liver disease according to (a) age, sex, obesity, body mass index (BMI) and metabolic syndrome (MetS), and (b) MetS components in the Kailuan cohort, adjusted for age (<45, 45–<55, 55–<65, ≥65 years), sex, marital status (single, married, divorced/widowed/separated), education (illiterate/primary, junior high school, senior high school, college or higher), income (<600, 600–800, 800–1000, >1000 RMB), workplace (underground/surface), occupation type (mental labour/physical labour), current tobacco smoking (yes, no), perceived salt intake (low, medium, high), physical activity (no, occasional, always), sedentary duration (<4, 4–8, >8 hours per day), elevated ALT (>40 U/L), obesity (normal, simple central, simple overweight, both), elevated SUA (>357 μmol/ L for women and >420 μmol/ L for men), CRP (<1, 1–3, >3 mg/L), and MetS (no/yes). Yellow indicates habitual snorers compared with non-snorers; blue indicates occasional snorers compared with non-snorers. Significant P values are shown for interaction on a multiplicative scale.
