Whole group—n = 47 at 18 months and 17 at 36 months. HL-only group—n = 30 at 18 months and 11 at 36 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.
