Practice parameter: Management of dementia (an evidence-based review)
Abstract
To the Editor: In the recently published “Practice parameter: Management of dementia (an evidence-based review),”1 the evidence for vitamin E was given significantly greater credibility than the comparable, if not greater, evidence for ginkgo biloba extract (GBE). The reviewers considered vitamin E a guideline but the single controlled trial2 was much less conclusive than the practice parameter suggests. The uncorrected, first-pass data analysis revealed no significant ( p < 0.05) beneficial effect of vitamin E. After correction for a slight baseline difference among the four groups in the Mini-Mental State Examination (MMSE) score ( p = 0.1), the selegeline, vitamin E, and combined groups had slightly better outcomes as defined by death, nursing home placement, conversion to Clinical Dementia Rating score three, or decrease in activities of daily living. Concerns about the analysis have already been raised.3 Additionally, there were no significant effects on cognitive measures in the study, certainly raising the possibility that any poorly defined effect of vitamin E on the outcome measure may have nothing specifically to do with AD. Whereas the combined outcome measure has public health implications, it is affected by types of behaviors and clinical events other than severity of AD that contribute to nursing home placement and death; e.g., aggressive behaviors, incontinence, and vascular disease. It could be argued that all these factors should have been covariates in the analysis. Another formal …

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
