  1. χ2: Chi-square test; MC: Monte Carlo; t: Student’s t-test; SD: standard deviation; PD: Parkinson’s disease; Min.: minimum; Max.: maximum
  2. F: F for ANOVA test, pairwise comparison bet. Each two groups was done using post hoc test (Tukey)
  3. p: p value for comparing between the studied groups
  4. p1: p value for comparing between early PD patients and advanced PD patients
  5. *Statistically significant at p ≤ 0.05
