Appendix 1—table 2. Results of the adult male orphan model testing, in orphan mature males only, the effect of age at maternal loss on cortisol profiles.
’Adult male orphan model full’ refers to the full model ran with all the interactions considered. ‘Adult male orphan model reduced’ refers to the reduced model after removing the interactions for which the 90% credible interval (CI) overlapped 0.SE indicates the standard error of the estimate for each predictor. The coded level for each categorical predictor is indicated in parentheses. Control predictors are italicized. 95% CI low and 95% CI high indicate the lower and upper limits of the 95% CI. Likewise, 90% CI low and 90% CI high indicate the lower and upper limits of the 90% CI. CIs that do not overlap 0 are indicated in bold. LCMS: liquid chromatography mass spectrometry. Time of the day2: quadratic term for time of the day. Time of the day3: cubic term for time of the day.
