  1. Model 1 was unadjusted, without controlling for any confounding factors; Model 2 adjusted for age and gender; and Model 3 was fully adjusted for age, gender, smoking status, alcohol consumption, hypertension, CHD, DM, and HYP. The regression coefficient (β) represents the change in hearing threshold (dB nHL) per 1-SD change in FDv.
