Figure 1  The relationship between asthma symptoms scores calculated by the G scale and ACT sum score.
Notes: (A) The asthma symptoms score is well correlated with ACT sum score. Spearman’s rank correlation coefficient is −0.743 (P<0.01). (B) The receiver operating characteristic curve is shown to determine a cut-off value of the asthma symptoms score calculated by the G scale, to identify asthmatic patients who are uncontrolled.
Abbreviations: ACT, asthma control test; G scale, frequency scale for the symptoms of asthma and rhinosinusitis developed in Gunma.
