Figure 1From: Association between leukocyte telomere shortening and exposure to traffic pollution: a cross-sectional study on traffic officers and indoor office workers Differences in leukocyte telomere length between (A) indoor office workers (referents) and traffic officers; and (B) traffic officers with exposure to low and high traffic intensity during their work shift. The graphs show geometric means (bars) 95% confidence intervals (lines) of telomere length adjusted by age, gender, smoking (ever/never), and pack-years.Back to article page
