Effect estimates (95% CI) of hearing thresholds (dBHL) with IQR increment in occupational noise exposure (dBA).

CI, confidence interval. aModel A was a crude model. bModel B was adjusted for age, age2, sex. cModel C: Model B + further adjusted for BMI, hypertension. dModel D: Model C + further adjusted for occupational exposures to organic solvents and heavy metals. eHearing Thresholds (dBHL) change per interquartile range (IQR) of occupational noise, 94.26 dBA - 84.74 dBA: 9.52 dBA. fPTA (pure tone average at 2, 3, 4 kHz). *p<0.05.
