Summary of the population parameters.

β0 is the logit-transformation prevalence of the outcome disease in people with homozygous major and the moderators in the study population. β1 is the log-transformation OR of the allele effect in people without moderators. β2 is the log-transformation OR of moderators on the disease in people with homozygous major, and β3 is the log-transformation moderator effect. Fst is the frequency difference among various studies, and P7, P8, and P9 are the proportions of moderators status in people with homozygous major [p(x2 = 1|x1 = 0)], people with heterozygous genotype [p(x2 = 1|x1 = 1)], and people with homozygous minor [p(x2 = 1|x1 = 2)], respectively.Summary of the population parameters.
