Reference for minor and major complications was no complications (n=470). Differences between complication groups were tested using multinomial logistic regression analysis. Model 1 was adjusted for age, body mass index, and comorbidity (cardiovascular disease, asthma/COPD, DM, other). Model 2 was adjusted for operative details [laterality, resected tissue (resg upper quartile), drain, operating surgeon]. N, number of participants; n, number of participants in the subgroup; OR, odds ratio; CI, confidence interval; COPD, chronic obstructive pulmonary disease; DM, diabetes mellitus.
