Difference in severity of side-effects, expressed as GEE regression coefficients, between low-expressing (GG) and high-expressing (AA/AG)) genotype groups for the HTR2A receptor. The comparison between groups for diminished sexual desire is statistically significant at p<.05 between GEE regression coefficients for low- and high-expressing genotypes. A Z test was used to test for the equality of regression coefficients (30).
