CC CT TT C T
EOPD 166 156 (94.0) 9 (5.4) 1 (0.6) 0.176a (df = 2, OR*) 321 (96.7) 11 (3.3) 0.296b (df = 1, OR = 0.669)
Controls 195 176 (92.3) 19 (9.7) 0 371 (95.1) 19 (4.9)
LOPD 348 318 (91.4) 29 (8.3) 1 (0.3) 0.487c (df = 2, OR*) 665 (95.5) 31 (4.5) 0.671d (df = 1, OR = 0.897)

  1. p-Values after correcting by binary logistic regression with age and gender using SPSS17.0.
  2. a p = 0.423; b p = 0.432; c p = 0.665; d p = 0.668.
  3. EOPD, early onset Parkinson’s disease (age at onset ≤ 50); LOPD, late onset Parkinson’s disease (age at onset > 50).
  4. *With df = 2, the OR value could not been given by Chi-square test.
