Data are presented as coefficient (95% CI). All models controlled for children’s sex, age, standing height, weight, 3-day mean concentration of ozone, 3-day mean concentration of nitrogen dioxide, 3-day mean of relative humidity, city and medication use as fixed effects. PEF: peak expiratory flow; FEV₁: forced expiratory volume in 1 s. ^#: lag exposure of temperature (0: exposure of current day’s temperature; 1: exposure of temperature on the previous day; 2: exposure of temperature 2 days previously; 3: exposure of temperature 3 days previously). *: p<0.05; **: p<0.01.
