↵* Subjects with rare variants (42) and samples with missing AAT levels (34) were excluded.
↵† Adjusted for age, sex, area, alcohol consumption (yes/no), systolic blood pressure, body mass index, smoking habit (never, former, current) and C-reactive protein levels.
↵‡ Additionally excluded were subjects with missing covariate data (212) and ZZ genotype due to insufficient frequency (1).
