Figure 1. Prevalence of depressive mood symptoms based on the severity according to Beck Depression Inventory (BDI) score between restless legs syndrome (RLS) and non-RLS groups. A: Graphical representation of the prevalence of depressive mood symptoms according to the BDI score between groups. The prevalence indicates accumulated prevalence over cutoff of the BDI score for mild (10≤BDI score), moderate (16≤BDI score), and severe depression (24≤BDI score). B: Graphical representation of prevalence of the severity of each depressive mood symptom among the groups: Mild depression (10≤BDI score<16), moderate depression (16≤BDI score<24), and severe depression (24≤BDI score).
