Table 4. Tests of interaction.
| Outlier status | Genetic component | a | b | ORa | v | ORb | Uncorrected Pinteraction | Corrected Pinteraction BC | |
|---|---|---|---|---|---|---|---|---|---|
| PRO | R | Western | v | Asian | 1.11 | v | 0.83 | 0.30 | >1 |
| PSO | R | Western | v | Asian | 1.12 | v | 1.11 | 0.97 | >1 |
| PRO | R | Western | v | African | 1.11 | v | 1.03 | 0.64 | >1 |
| PSO | RX | Asian | v | Western | 1.91 | v | 1.03 | 0.012 | 0.06 |
| PSO | R | Female | v | Male | 1.58 | v | 1.06 | 0.007 | 0.03 |
PRO: pre-outlier; PSO: post-outlier; R: common allele; RX: heterozygous genotype; v: versus; OR: odds ratio; a: subgroup with significant ORs; b: subgroup with non-significant ORs; P-values were Bonferroni-corrected (BC). Values in bold indicate significance (P < 0.05) of associations (under ORa) and P-values (corrected and uncorrected)
