The association between rs53576 polymorphism and close relationship.

<p>A) Magnitudes of effect size for the association between rs53576 polymorphism and individual differences in close relationship are illustrated by the forest plot (AA + GA vs. GG). Boxes represent the effect size (Cohen’s <i>d</i>) for each sample in the analysis; the size of the boxes represents the weighting for each study; lines represent the .95 confidence interval for each effect size; and the diamond represents the overall effect of the meta-analysis, which was obtained by a random effects model. B) Publication bias is illustrated by the funnel plot. The horizontal axis represents the effect size of each study, and the vertical axis represents the size of each study (indexed by the standard error of the effect size within each study).
