All continuous variables in the table were nonnormally distributed and described as median (interquartile). ^aAPOE genotype results were included in the convenience sample SCD subjects (), ε4⁺ (). ^bSTT-B results were included in the convenience sample () and in population-based samples (). ^cThe value was calculated using Chi-square. ^dThe value was calculated using the Mann-Whitney . ^eThe value was calculated using independent samples tests.
