Group = Early compared to late-onset depression,
p <.05,
p<.01.
MADRS= Montgomery Asberg Depression Rating Scale
MMSE=Mini–Mental State Examination
R (Right), L (Left)
NONLGM = Gray matter excluding lesions
WMLES = White matter lesions
GMLES = Gray matter lesions
HIPPOC = Hippocampal volume
NONLWM = White matter excluding lesions,
LNONLWM = White matter excluding lesions
Note: The first column `Group' shows if, at baseline, the dependent variables differed between EOD and LOD participants. The second column `Group × Time' reports the interaction of depression group (LOD vs. EOD) over time and indicates if one group changed more than the other group over time. The third column labeled `Group × Attrition' shows if the effect of group differs based on if the participant left the study early. The final column labeled `Group × Time × Attrition' shows if the interaction of group and time was different among participants who left the study early.
