Neuropsychological Impairment Following Traumatic Brain Injury: A Dose-Response Analysis
Abstract
Dikmen, Machamer, Winn, and Temkin (1995) administered the Halstead-Reitan Battery (HRB) to a sample of TBI patients. Similar patients were obtained from the second author (JEM) for two main purposes. First, we wished to determine if there is a dose-response relationship between TBI severity and residual cognitive deficit. Second, are Dikmen et al. results generalizable to other TBI samples? Analyses of the Meyers sample replicated the analyses of Dikmen sample. A significant dose-response relationship between loss of consciousness (LOC) and cognitive impairment was found using effect sizes for the Dikmen sample, as well as using regression-based normative T scores for the Meyers sample. The two methods were highly correlated with one another. Using mean scores for the six LOC-severity groups and the two samples resulted in a correlation coefficient r=.97, p<.0001. Results are presented for clinicians to use when assessing individual patients.

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.
