N = 54 at 18 months, 37 at 36 months, and 25 at 54 months. Higher Ed: More than 12 years of education. Bolding denotes significant p-value after Holm–Bonferroni correction. Abbreviations: Mean dep, mean, dependent variable; SD dep, standard deviation, dependent variable. For Age 70, female, and Higher Ed, p values are reported but are not evaluated for significance. These variables have been treated as controls, not variables of interest.
