CN, EOAD, and EOnonAD demographic and cognitive summaries, presented as mean (standard deviation, and comparisons. The last three columns represent t-statistics (p-values) from analyses comparing the respective groups for continuous variables, while binary variable comparisons show test statistics (p-values) from Chi-squared tests.
