  1. All p-values were obtained from a between group one-way Analysis of Variance test, unless otherwise specified.
  2. LLD late-life depression, NC normal control, SD standard deviation, MMSE mini-mental state examination, NA not applied, GDS Geriatric Depression Scale.
  3. aFisher's exact test. A p-value of < 0.05 denotes no relationship between gender and group, expressed as the sum of probabilities obtained from a permutation procedure of all the gender x group contingency tables less likely than or equal likely to the observed table.
  4. bTest statistic value is not reported, as the Fisher's exact test performed for gender calculates a sum of frequency probabilities from a permutation procedure to estimate the p-value, rather than a test statistic.
