Abstract

(2002) Neurology 58, 527; The Tourette’s Syndrome Study Group. . Treatment of ADHD in children with tics. A randomized controlled trial. . Feb 26; . : . –36 . [OpenUrl][1][Abstract/FREE Full Text][2] QUESTION: In children with attention deficit hyperactivity disorder (ADHD) and Tourette’s syndrome (TS), what is the effect of clonidine (CLON), methylphenidate (MPH), or combined CLON and MPH? Randomised (allocation concealed*), blinded {patients, clinicians, data collectors, outcome assessors, data analysts, data safety and monitoring committee, and manuscript writers}*†, placebo controlled trial with 16 weeks of follow up. 11 sites in the US. 136 children between 7 and 14 years of age (mean age 10 y, 85% boys) who had ADHD of any subtype and TS, chronic motor tic disorder, or chronic vocal tic disorder. Exclusion criteria included secondary tic disorder, major depression, pervasive developmental disorder, autism, mental retardation, anorexia nervosa, and bulimia. Follow up was 86%. Children were allocated to receive CLON alone (n=34), MPH alone (n=37), combined CLON and MPH (n=33), or placebo (n=32). … [1]: {openurl}?query=rft.jtitle%253DNeurology%26rft.stitle%253DNeurology%26rft.issn%253D0028-3878%26rft.volume%253D58%26rft.issue%253D4%26rft.spage%253D527%26rft.epage%253D536%26rft.atitle%253DTreatment%2Bof%2BADHD%2Bin%2Bchildren%2Bwith%2Btics%253A%2BA%2Brandomized%2Bcontrolled%2Btrial%26rft_id%253Dinfo%253Apmid%252F11865128%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/ijlink?linkType=ABST&journalCode=neurology&resid=58/4/527&atom=%2Febmed%2F7%2F5%2F157.atom

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
