  1. RR relative risk;Crude model only included the association between O3 exposure concentration and KD in children; Model 1 adjusted for age, sex, medical history, blood routine, and other factors based on the crude model; Model 2, we excluded the data of 40 days before and after New Year’s Eve and re-estimated the O3 concentration; Model 3 we adjusted it into the multi-pollutant model; Model 4 we excluded participants with infection-induced disease and reanalyzed the association between O3 and KD.
  2. Bold values represent statistical significance p < 0.05.
