The values: β are presented as the standard regression coefficient (p-value). Age, sex, hemoglobin, albumin, and average plasma glucose (or HbA1c) were adjusted for in the analysis. The symbol ○ indicates that the stepwise multiple regression analysis was conducted by using all variables listed in this table
GA, Glycated albumin; HbA1c, glycated hemoglobin; FT3, free triiodothyronine; HD, hemodialysis; DM, diabetes mellitus; Ob.va, objective variable; Ex.va, explanatory variable; Av-PG, average plasma glucose; Hb, hemoglobin; Alb, albumin; R², multiple coefficient of determination; R*², adjusted multiple coefficient of determination
