Subjects characteristics of the study populations.
Fig 1.
Skin autofluorescence stratified for smoking class (LifeLines Cohort Study).
Bars represent mean SAF Z scores (adjusted for age, creatinine clearance and diabetes), whiskers reflect standard error of the mean. Never smoker (n = 3670), Former smoker (n = 3321), Light smoker (0–10 gram tobacco per day, n = 878), Moderate smoker (10–20 gram tobacco per day, n = 537), heavy smoker (>20 gram tobacco per day, n = 475). SAF, skin autofluorescence; AU, arbitrary units; NS, not significant.
Fig 2.
Effect of smoking cessation on skin autofluorescence in former smokers participating in the LifeLines study.
Dots show mean SAF Z-scores (adjusted for age, BMI, creatinine clearance and diabetes status). Whiskers reflect standard error of the mean. SAF, skin autofluorescence
Fig 3.
Effect of secondhand smoking on skin autofluorescence in never- and former smokers participating in the LifeLines study.
Bars represent mean SAF Z scores (adjusted for age, creatinine clearance and diabetes status) in never smokers and former smokers who stopped smoking for more than 15 years, whiskers reflect standard error of the mean. 0 hours (n = 4213), 1–5 hours (n = 676), 6–10 hours (n = 78), >11 hours (n = 15). SAF, skin autofluorescence; Arbitrary Units, AU; NS, not significant.
