*Models were adjusted for age, sex, race, pack-years, current smoking status, BMI, and FEV₁% predicted, excluding the variable that was used to define the strata (e.g. models in obese and non-obese subjects were not adjusted for BMI). Odds ratio is for non-emphysematous compared to emphysema-predominant COPD.
