*Benjamini-Hochberg rejects all p values above 0.0321 to control the FDR at 0.05.
†A test for differences between the three groups adjusted for sex, age, region of residence, social group, living alone, smoking status, pack-years, motivation for smoking cessation and the CCI. The continuous values variables (age and pack-years) are included as a quadratic function as to allow for possible non-linear effects.
