T2DM: Type 2 Diabetes Mellitus; OR: Odds Ratio; CI: Confidence Interval. Models were adjusted for sex, age, ethnicity, individual income and NO2. This paper has been recommended for acceptance by Dr. Payam Dadvand.. The median of dynamic road and aircraft noise exposure was 0.13 and 0.10, respectively..
