Data extracted from RCTs investigating the therapeutic effects of vitamin B12 alone (B12 alone) and vitamin B12 in addition to vita-min B9 (folic acid) with or without vitamin B6 (B complex) on measures of cognitive func-tion, depressive symptoms, and fatigue in patients with or without mild cognitive im-pairment (MCI)
