VaP group showed significantly lower serum haemoglobin (p = 0.005), albumin (p < 0.001), and HbA1c (p = 0.014) and higher uric acid (p = 0.015), cholesterol (p = 0.002) and low-density lipoprotein (LDL) (p = 0.012) than PD group (Supplementary Table 2). This evidence concerns the gene ALB and Parkinson disease.
