Correlation between SOD activity and glycated haemoglobin. Data correlation between the values of glycated haemoglobin (HbA1c %) and serum superoxide dismutase activity (SOD) in both types of diabetes mellitus. The correlation coeficients (Spearman) are r1 = -0,41 (T1DM), r2 = -0,23 (T2DM) with p < 0,05. Dotted lines mean 95% confidence intervals.
