FIG 2.
The probability of asthma remission by adulthood increases as baseline FEV1/FVC ratio increases. When the baseline FEV1/FVC ratio was at least 85%, the probability of asthma remission is dependent on baseline PC20 and serum eosinophil counts. In this subgroup the probability of asthma remission was 58.3% when the baseline PC20 was less than 1 mg/mL. When the baseline PC20 was greater than or equal to 1 mg/mL, the probability of asthma remission was 65.4% in those with peripheral eosinophilia and 82.6% in those without peripheral eosinophilia.
