showed a trendp = 0.277
The comparison of the frequencies of the H1j/H2 diplotype between sporadic idiopathic PD (3/80) and control subjects (1/92) showed a trend of association since the odds ratio was 3.35 which remains still not significant (3.75 vs. 1.0%; OR, 3.55; 95% CI, 0.36–34.78; p = 0.277) due to the rarity of the diplotype and the small size of the samples.
