Relative risks (RR) for asthma admissions for a 10 (PM10) or 5 unit (NO2) and IQR, adjusted for day of the week, national holiday, temperature, humidity, season and wind speed, 2017–2019: two-pollutant model* results (children; 0–4 years)

RR95% CIP value
PM10 (10 µg/m3 increase)0.970.95 to 0.990.028
NO2 (5 µg/m3 increase)0.980.96 to 0.990.011
PM10 (IQR; 25.1 µg/m3)0.930.87 to 0.990.029
NO2 (IQR; 16.5 µg/m3)0.930.88 to 0.990.012
  • *PM10 and NO2 mutually adjusted for; collinearity of variables was not found (variance inflation factors (VIF)>4 observed in linear regression analysis when PM10 and PM2.5 included in the same model).
