Cumulative transition probabilities of T2D for participants exposed to different levels of air pollution. Computed for 55-year-old men (continuous) and women (dotted) for values of air pollution of quartile 1 and quartile 4. Quartile cutoffs were 2.92–13.23 μg/m3 and 16.48–28.48 μg/m3 for PM10, 1.69–8.74 μg/m3 and 11.05–18.70 μg/m3 for PM2.5, 3.75–19.79 μg/m3 and 32.22–111.01 μg/m3 for NOx, and 2.86–14.17 μg/m3 and 21.25–57.92 μg/m3 for NO2, respectively. The model was adjusted for age, sex, ethnicity, living area, smoking status, healthy diet, physical activity, and family history of diabetes. Abbreviation: T2D, type 2 diabetes
