aTotal baseline population: participants in 1989–92 in RHINE, 1991–93 in Italian ECRHS, 1998–2000 in ISAYA. 10-yrs follow up population: participants in 1999-2000 in RHINE and 1998–2000 in Italian ECRHS, 2008–09 in ISAYA. 20-yrs follow-up population: participants in 2010-12 in RHINE, 2008–09 in Italian ECRHS. bCorrected for inter-dependency between long-term participants and total baseline participants, by using a non-parametric bootstrap method. Significant associations between risk factors and respiratory symptoms are marked in bold font, as well as significant differences between long-term participants and all baseline participants.
