Notes:

See list in Table 1.

^{^}

Includes one study that did not specify genotype frequencies by sex.

1. When a sample included multiple measures, N for measure with biggest sample size (specific to each sex category) was used to calculate the Ns reported here. Sex-specific Ns are only based on studies that provided sex-specific data.

2. Percentages given as row total for each ethnicity.
