  1. Note. Solvent exp: EXP: solvent-exposed group, NEXP: non-exposed group (reference); Tenure: number of years working at the factory exposed to solvents; Cigarettes: Number of cigarettes smoked per week; Alcohol: Number of drinks per month; Shoot WP: history of shooting practice wearing hearing protection; ShootNP: history of shooting practice without wearing hearing protection; No shoot: absence of shooting practice (reference); Pastnoise: history of previous occupational noise exposure; Interaction Age*solvent: factor of age times solvent group (exposed versus non-exposed).
