Table 3 Results of a Hierarchal Multiple Regression (HMR) model within the asthma subgroup, with Generalized Anxiety Disorder Assessment-7 (GAD-7) score as the independent variable (n = 231). Asthma Control Questionnaire-6 (ACQ-6) scores did not significantly improve the predictive value of Model 2a after being added in Model 2b (ΔR2 = 0.007, F(1,220) = 2.48, p = .117)
