Change in prevalence of smoking (A and B) and ever smoking (C and D) with ageing during follow-up in generations aged 20–29 (− + −), 30–39 (−─–), 40–49 (−✻–), 50–59 (−▲–), 55–59 (− × −)*, 60–69 (−♦–), 70–79 (−●–) and 80–89 (−■–) years at baseline for men (A and C) and women (B and D) separately. Open markers and dotted lines represent groups consisting of less than 50 participants. *During the second wave of the LASA study, participants aged 55–59 at baseline were not invited for the medical interview, which explains the missing link between the first and the third data point for this generation.
