We discovered that levels of the CRP (47.91 ± 36.27 vs. 27.46 ± 19.65, p < 0.0001), ALB (3.89 ± 0.78 vs. 6.19 ± 0.37, p < 0.0001), white blood cells (WBC) (8.68 ± 2.83 vs. 7.92 ± 1.93, p = 0.026), and LYM (2.67 ± 0.89 vs. 2.27 ± 0.71, p < 0.0001) were significantly different between the two groups (T2DM vs. preDM). Here, CRP is linked to type 2 diabetes mellitus.
