Figure 7. Correlation analysis showed that sIL-6R concentrations in AqH were positively correlated with the BMI (r = 0.121, p = 0.136), duration of diabetes (r = 0.464, p<0.001), FPG (r= 0.407, p<0.001), and HbA1c (r = 0.458, p<0.001) in patients with T2DM. Data were analyzed by using a Spearman’s rank correlation test.
