Results presented in Web Table 1 suggest that during the first 5 years of follow-up (1998-2002) COPD might have been under-diagnosed; the HRs among men who consumed 14.1–20 and >20 drinks/week were lower in comparison to those observed in the last 6 years of follow-up (2009-2014). To address the possible impact of under-ascertainment of COPD on observed risk estimates we then excluded the first 5 years of follow-up; however, the HRs of COPD by categories of total alcohol consumption did not change substantially and were 1.13 (95% CI=0.94–1.35) among men with weekly alcohol consumption of <1 drink; 1.14 (95% CI=0.99–1.32) among those who consumed 1–3.9 drinks; 1.23 (95% CI=1.01–1.48) among those who consumed 14.1–20 drinks; 1.38 (95% CI=1.15–1.65) among those who consumed >20 drinks and 1.40 (95% CI= 1.12–1.77) among past drinkers as compared to men who consumed 7–14 drinks/week.
