WebPatients with recorded PEFR < 80% of their best value were excluded from the study. After the 4-week run-in period, the study subjects were separated into two groups: one group of patients had a meanβ 2 -agonist consumption of > 1 puff/d (high consumers); the other group had a meanβ 2 -agonist consumption of ≤ 1 puff/d (normal consumers). WebSaO 2 and PEFR% were significant predictors of high uric acid (R 2 =0.50, P <0.001) in model 2. The sensitivity and specificity of sUA in predicting severity of asthma at the cutoff point of 6.3 mg/dL were 80% and 90%, respectively. The odds ratios of sUA, number of asthma exacerbations, and asthma duration were 5.4, 1.95 and 1.3, respectively.
