In the rank‐difference Spearman correlation analysis, the coefficient of correlation |r| value is low for P values with many patients. The items with P < 0.05 are displayed in bold.

In the multiple regression analysis, the l‐dopa + assist drug LED and agonist LED were excluded by multicollinearity leftacteristics. The items with P < 0.05 are displayed in bold.
