Table 7.
Results for GSTM1 and Autism Association Study. "Pearson" refers to Pearson's chi-square analysis of the case-control data. "Likelihood Ratio Test" refers to the 1-df test discussed in the text, in this case using the full information in Table 6. OR = Odds Ratio, RR = Relative Risk of homozygous deletion genotype relative (r1 in the text).
| Method | Pearson | Likelihood Ratio Test |
| Chi-square | 4.84 | 3.97 |
| p | 0.028 | 0.046 |
| Effect Size (95% Conffidence Interval) | OR = 2.02 (1.03; 4.04) | RR = 1.85 (1.07; 3.30) |
| Null allele frequency | 0.69 | 0.71 |
