Spearman’s correlation analysis showed that, in the T2DM group, the PTX3 levels correlated more strongly with new hematological indices (IIC, rho = 0.445, p-value = 0.014; MCVL, rho = 0.338, p-value = 0.048) and established hematological markers (NLR, rho = 0.367, p-value = 0.050; MLR, rho = 0.382, p-value = 0.037; AISI, rho = 0.279, p-value = 0.035) (Figure 3). Here, PTX3 is linked to type 2 diabetes mellitus.
