Additional file 1: of Air pollution and airway resistance at age 8 years – the PIAMA birth cohort study

Table S1. Land-use regression models with model performance (leave-one-out cross-validation R2, R2LOOCV), Table S2. Comparison of characteristics between the study population (n = 983) and the full PIAMA cohort (n = 3963). Table S3. Distribution of daily average air pollution concentrations, temperature and relative humidity on the day of the Rint measurements. Table S4. Spearman correlations between annual average air pollution concentrations at the participants’ birth and current addresses. Table S5. Correlations of estimated annual average air pollution concentrations at the birth and current address at the time of the 8-year Rint measurements with daily average air pollution concentrations on the day of the Rint tests. Table S6. Associations * between change in Rint from age 4 to age 8 years (Rint age 4 – Rint age 8) and estimated average air pollution concentrations during the period between the two Rint measurement from single-pollutant models. Figure S1. Smoothing splines of the relationship between annual average air pollution concentrations at the birth address and Rint at age 8 from single-pollutant models. Figure S2. Smoothing splines of the relationship between annual average air pollution concentrations at the current address at the time of the Rint measurement and Rint at age 8 from single-pollutant models.
