Results are proportions, indicated as percentages, except for MTA L and MTA R. AD and MCI group means and proportions were compared to SCI. p values correspond to χ² tests or binary logistic regression, as appropriate. MTA L = Blinded MTA rating on the left side (average); MTA R = blinded MTA rating on the right side (average).
