Statistical parameters characterizing the PNA phenotype (Fig. 1)
| Property | Two-tailed unpaired Welch- corrected Student’s t test | Mean difference | Effect size, Cohen’s d | ||
|---|---|---|---|---|---|
| Anogenital distance (mm) | t(30.13) = 10.052, p < 0.0001 | Diff 2.06 [CI 1.64, 2.48] | d = 3.03 | ||
| Body mass (g) | t(32.03) = 2.331, p = 0.0262 | Diff 2.26 [CI 0.29, 4.24] | d = 0.707 | ||
| Property | χ2 test | Estrus | Diestrus | Proestrus | |
| Estrous cycle stage distribution | χ2 = 111.392, n = 992, df = 2, p < 0.0001 | Std resid: | −1.79 | 7.08 | 10.11 |
| Fisher’s exact test; Bonferroni adjusted: | p = 0.226 | p < 0.0001 | p < 0.0001 | ||
Bold indicates p < 0.05. Std resid, standardized residuals of PNA group from χ2 test.
