Notes: Linear models adjusted for age, gender, and education. TMT = Trail Making Test; RAVLT = Rey Auditory Verbal Learning Test. Higher scores on all test indicate better performance except for TMT A and B, for which higher scores equal worse performance. BF = Bayes Factor; β = standardized regression coefficient; R2s = unique variance accounted for via Shapley decomposition of R2. 95% CI = 95% Confidence Interval, based on robust standard errors for β and bootstrap percentiles for R2s. P-values from t-test with 178 degrees of freedom for all outcomes, except for Trails A and Category Fluency (177) and Trails B (176). Strong evidence for association based on p-values exceeding rejection threshold of FDR (.011) and Bayes Factors > 20; Moderate evidence for association based on p-values exceeding FDR threshold and Bayes Factors 3–20; Mildly suggestive evidence for association p-values exceeding conventional or FDR threshold, positive but anecdotal Bayes Factors.
