  1. Z-scores of the projected weights are shown for each sub-cohort and component (mean ± std. dev.). Significant differences (p < 0.005) are highlighted in bold-face. Scheffé’s multiple-comparison post-hoc tests are represented by super-indices indicating differences between the labeled sub-cohorts at an α-level of 0.005 (when significant differences were found in categorical variables). Sub-cohorts may not add to 1991 due to missing data.
