Validation of cognitive metrics. Each box represents Pearson’s correlation coefficient of baseline Montreal Cognitive Assessment (MoCA) subscores and domain Z-scores using full cognitive testing. Significance (*) indicates p-value < .05. Attention/executive function tests included Dementia Rating Scale 2-attention subscore, Stroop color-word test, and a Letter-Number sequence task. Memory tests included the Brief Visuospatial Memory Test, Hopkins Verbal Memory Test, and a visual-verbal memory task. The MoCA subscores are made up of the sum of trails, clock drawing, digit span, letter tapping, and serial 7s scores for attention/executive subscore and the sum of delayed recall and orientation scores for memory subscore.
