Notes: Means (standard deviations) are reported. The number of subjects included in the analysis is reported for each cognitive variable. # The result was no longer significant after Bonferroni correction for multiple comparisons. MMSE: Mini-Mental State Examination; Rey figure: Rey–Osterrieth complex figure; ECT: electroconvulsive therapy.
