Effect of each variable on the amount of change in the DAI-10
REGRESSION
A multiple regression analysis was performed using a stepwise method with the change in DAI-10 as the dependent variable and PHQ-9, EQ-5D, patient satisfaction, as independent variables. As a result, only the change in patient satisfaction (standardized coefficient β: 0.450, p = 0.024) was included in the model. The adjusted R-squared value was 0.203. A list of the excluded variables and their variable correlation coefficients and significance probabilities is provided as a supplemental document.
