Notes: aFrom a model with current smoking, former smoking, gender and age; bIntroduced as a single variable in a model adjusted for smoking, gender and age; cIn the gender-stratified data, the models comprised current smoking, former smoking, age, and the single symptoms/diseases. Bold text indicates statistical significance.
Abbreviations: VGDF, vapor, gas, dust or fumes; COPD, chronic obstructive pulmonary disease.
