Odds ratio (95% confience interval), the interquartile range was increased after 19 and 24 h to O 3. Results: The effect was lag 25 and 48 h in winter for ozone (O3). The effects for O3 were to the age of low socioeconomic status modifid lag 7e12 h (1, 252 (1:04 and 1:51)). The O3 increased the risk of asthma exacerbations.
