  • Data are means ± SD or n (%), with percentages based on the total number in the corresponding column, unless otherwise indicated. Test of equality across groups based on regression models. Data gathered from PROSPECT. The ranges of scores are 0–30 for the Mini-Mental State Examination (MMSE), with high scores indicating less severe cognitive impairment.; 0–76 for the Hamilton Depression Rating Scale (HDRS), with high scores indicating greater depressive symptoms; and 0–38 for the Scale for Suicidal Ideation (SSI), with high scores indicating greater suicidal ideation.
