Figure 1

Time course changes in peak expiratory flow rate (PEFR) in asthmatic patients (𝑛=30) before acute asthma exacerbations (baseline) and after treatment with oral glucocorticoids. ↑: the start of treatment of acute asthma exacerbations with oral glucocorticoids. Means and ranges are indicated by open circles with bars. Significant differences from baseline are indicated by **𝑃<0.01. Significant differences from acute asthma exacerbations are indicated by ⁺𝑃<0.05 and ⁺⁺𝑃<0.01. (Cited from [19]).
