Demographic and clinical characteristics of the study group by smoking status.
Fig 1.
Prevalence of clinical lung diseases by smoking status and pack-years groups.
The letters represent each group and when placed on the top of a bar it represents a statistical difference between that bar and the group the letter represent.
Fig 2.
Prevalence of subclinical lung conditions by smoking status and pack-years groups.
The letters represent each group and when placed on the top of a bar it represents a statistical difference between that bar and the group the letter represent.
Fig 3.
Prevalence of multimorbidity lung diseases by smoking status and pack-years groups.
The letters represent each group and when placed on the top of a bar it represents a statistical difference between that bar and the group the letter represent.
