  • *The sample size may vary for some variables, because of missing values. Means and SD are presented for normally distributed continuous variables. Medians and IQR are presented for skewed continuous variables. Frequencies and proportions are presented for categorical variables. Differences in mean were tested using Independent-Samples T-test for normally distributed continuous variables, differences in median were tested using Mann-Whitney U test for skewed continuous variables and differences in frequencies were tested using Pearson χ² test.

  • dB(A), A-weighted decibels; GECCO, Geoscience and Health Cohort Consortium;  n, number of observations; NO2, nitrogen dioxide; NOx, nitrogen oxides; PC4, 4-digit postal code; PC6, 6-digit postal code; PMcoarse, particulate matter with diameter 2.5–10 µm; PM2.5, particulate matter with diameter ≤2.5 µm.
