The Low Level of Response Model (LLRM) and Differentiator Model (DM) were originally developed to explain differences in subjective response among FH+ men. As would be expected by both models, sample gender significantly affected the size of the FH difference, Qbetween(1) = 4.99, p = .03. In male samples, subjective responses were approximately 0.53 standard deviations lower among FH+ relative to FH−, g = −0.53 (95% CI: −0.96, −0.10), although significant between-study heterogeneity remained, Qwithin(9) = 25.88, p = .002, I2 = 65.23. For male samples only, the fail-safe N was 38. In contrast, there was very little effect of FH in samples containing women, g = 0.01 (95% CI: −0.19, 0.21), nor was there significant heterogeneity across studies, Qwithin(8) = 8.27, p = .41, I2 = 3.21.
