Methylphenidate vs Dextroamphetamine vs Caffeine in Minimal Brain Dysfunction: Controlled Comparison by Placebo Washout Design With Bayes' Analysis

Arnold, L. Eugene·1978·Archives of General Psychiatry

Abstract

Double-blind crossover comparison of methylphenidate hydrochloride, dextroamphetamine sulfate, and caffeine after placebo washout in 29 children with minimal brain dysfunction (MBD) showed on six ratings that methylphenidate and dextroamphetamine were significantly (P less than .05 to P less than .001) better than placebo and caffeine, but not significantly (P less than .05) different from each other. Placebo, caffeine, and ratings before drug did not differ significantly. Of 26 drug responders, 12 responded best to dextroamphetamine, ten to methylphenidate, and one to caffeine. The latter child showed no improvement at all with either prescription stimulant. Methylphenidate and dextroamphetamine were each efficacious for six children who did not respond to the other stimulant. All three drugs showed significant (P less than .05) weight loss and cardiovascular side effects, the latter possibly spurious. Dextroamphetamine showed a significant (P less than .05) decrease from placebo in "tummyaches."

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.
