Table 3.

Statistical results from linear models run for Wave 12 performance on each of 6 cognitive tests. Each model had the form Test ~ LV 1 + LV 2 + Age + Sex + Education. Standardized beta coefficients and 95% confidence intervals are reported, where the standardized coefficient represents the change in wave 12 test scores for every one unit increase in LV scores, in units of standard deviation. Bold p-values are deemed significant at a Bonferroni-corrected threshold of p < 0.0083.
