Abstract

Objective Results of the NIMH Collaborative Multisite Multimodal Treatment Study of Children With Attention-Deficit/Hyperactivity Disorder (MTA) were analyzed to determine whether a double-blind, placebo-controlled methylphenidate (MPH) titration trial identified the best MPH dose for each child with attention-deficit/hyperactivity disorder (ADHD).Method Children with ADHD assigned to MTA medication treatment groups (n = 289) underwent a controlled 28-day titration protocol that administered different MPH doses (placebo, low, middle, and high) on successive days.Results A repeated-measures analysis of variance revealed main effects for MPH dose with greater effects on teacher ratings of impairment and deportment (F3 = 100.6, n = 223, p = .0001; effect sizes 0.8-1.3) than on parent ratings of similar endpoints (F3 = 55.61, n = 253, p = .00001; effect sizes 0.4-0.6). Dose did not interact with period, dose order, comorbid diagnosis, site, or treatment group.Conclusions The MTA titration protocol validated the efficacy of weekend MPH dosing and established a total daily dose limit of 35 mg of MPH for children weighing less than 25 kg. It replicated previously reported MPH response rates (77%), distribution of best doses (10-50 mg/day) across subjects, effect sizes on impairment and deportment, as well as dose-related adverse events.

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.
