GPT and Hyperglycemia: Compared with the RDW − CV ≤ 12.90 g/L group, the average age, male, HDL-C, Na, and Cl levels were remarkably increased, and the female, FBG, TG, and P levels were significantly decreased in the RDW − CV > 12.90 g/L group of patients with hyperglycemia (P < 0.05); no statistically significant difference was observed in the AST, ALT, Cre, UA, TC, F-CHOL, LDL-C, K, Ca, Mg, Zn, and BMI between the groups (Table 4 and Figure 4).
