The drop in peak expiratory flow (PEF) after exercise ranged from 0 to 79% of the baseline (mean 21.3%) and exceeded 12.5% in 52 (55%) patients. There was a small but significant correlation between the baseline FEV<jats:sub>1<\/jats:sub>\/FVC and MMEF values and the response to exercise (<jats:italic>r<\/jats:italic>=\u22120.39 and \u22120.35; <jats:italic>p<\/jats:italic>=0.000, respectively), but when studied by linear regression analysis, the response to exercise was best predicted by the past symptom rate and a concave pattern in the pre\u2010test maximal expiratory flow\u2013volume curve. The values of traditional lung function tests or age, atopy, duration of symptoms or history of exercise\u2010induced wheezing did not remain in the model.<\/jats:p><jats:p> <jats:bold>Conclusions:<\/jats:bold> These results show that the severity of asthma in school\u2010aged children can be predicted at the first visit based on the past rate of symptoms and a visual

curve.<\/jats:p>","DOI":"10.1111\/j.1651-2227.2005.tb01939.x","type":"journal-article","created":{"date-parts":[[2010,8,7]],"date-time":"2010-08-07T01:56:40Z","timestamp":1281146200000},"page":"559-563","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A
