Table 3 contains information about the laboratory results, which showed that the PD group had a higher white blood cell count (6.29 vs. 5.16 × 109, p = 0.001), higher neutrophil count (4.32 vs. 2.79 × 109, p = 0.001), lower lymphocyte count (1.33 vs. 1.38 × 109, p = 0.010), higher proportion of neutrophils (67.33% vs. 57.61%, p = 0.049), lower proportion of lymphocytes (21.53% vs. 28.20%, p = 0.036), a higher neutrophil-to-lymphocyte ratio (3.14 vs. 2.11, p < 0.001) and higher C-reactive protein levels (12.34 vs. 3.19, p < 0.001). Here, CRP is linked to Parkinson disease.
