Figure 1. Scatter plots depicting the correlation of HbA1c with age and RDW in the diabetic group (n = 150).

Figure 1

(A) Scatter plot showing the correlation between HbA1c and age in diabetic patients. A significant negative correlation was observed (r = -0.205, p = 0.012). (B) Scatter plot showing the correlation between HbA1c and RDW in diabetic patients. A weak but statistically significant positive correlation was observed (r = 0.126, p = 0.024). Pearson’s correlation coefficient was used to assess the associations

HbA1c: glycated hemoglobin; RDW: red cell distribution width; RDWcv: red cell distribution width - coefficient of variation
