Outcome on the Dementia Rating Scale (DRS) for low B12 (n=28) and normal B12 (n=28) subjects. Displayed values represent mean±SEM (SEM used for legibility). From 0 to 16 weeks low B12 subjects improved by 4.4±17.6 (SD) points, and normal B12 subjects declined by −2.0±9.9 points. However, this difference was not significant (F=3.24; df=1,53; p=0.077, ANCOVA) (Z=−0.97, p=0.33, Mann-Whitney U test).
