cOR = crude odds ratio aOR = adjusted odds ratio;

adjusted for age (years), sex, and average household income 10 years ago (<1000 = 1, 1000-2499 = 2, 2500-4999 = 3, ≥5000 = 4).

adjusted for pack years of smoking (continuous) and indoor air pollution (an index of 0 = none, 1-2 = low and 3-5 = high indoor air pollution) in addition to the covariates in Model 1.
