Note. Sig. GxE? = whether the primary G×E hypothesis was statistically significant; Eth. Het? = whether the sample was ethnically heterogeneous [U=unknown]; Proper Control? = whether the investigators included all relevant covariate-by-gene and covariate-by-environment interactions in the model testing G×E [N/A=Not Applicable because investigators did not attempt to control for any covariates].
