| σ2G (s.e.) | σ2G/σ2P (s.e.) | LRT (df=1) | P | |
|---|---|---|---|---|
| Entire sample (n=9633) | 4.79 (1.39) | 0.10 (0.03) | 13.65 | 0.0001 |
| Controls (n=4820) | 0.99 (0.88) | 0.07 (0.06) | 1.28 | 0.13 |

Abbreviations: EPQ, Eysenck Personality Questionnaire; df,degrees of freedom; LRT, likelihood ratio test; P, P-value for the LRT; SNP, single-nucleotide polymorphism; σ2G, genetic variance; σ2G/σ2P, proportion of total variation due to common genetic variants.
