Adjusted odds ratio for prevalence of hearing loss with different smoking intensity in middle-aged group and older group of males
| Variables | Middle-aged (n=489) (40–59 years) | Older (n=237) (60–80 years) | ||||
|---|---|---|---|---|---|---|

Smoking Index (SI): cigarettes/day multiplied by number of smoking years. AOR: adjusted odds ratio; adjusted for the covariates of age, education level, income level, drinking, workplace noise, frequency of earphone use, hypertension, diabetes, and hyperlipidemia.
