Abstract
BACKGROUND: The thrice daily dosing regimen of immediate release methylphenidate (IR-MPH) for Attention Deficit/Hyperactivity Disorder (ADHD) requires in-school dosing, leading to issues surrounding dispensing and storage of controlled substances by school personnel and concerns over children?s privacy and the embarrassment associated with taking medication in public at school. OROS-methylphenidate (OROS-MPH) is a once-daily controlled-release formulation of methylphenidate (MPH) developed to overcome some of the limitations associated with IR-MPH and first-generation sustained-release formulations. Randomized, controlled trials (RCTs) that focus on treatment efficacy provide the best evidence for demonstrating whether an intervention works, but under ideal conditions one cannot discount the importance of efficacy study results. However, the most useful information to clinicians comes from an effectiveness study design. OBJECTIVES: To evaluate the effectiveness and tolerability of OROS-MPH versus usual care with IR-MPH in children aged 6 to 12 years with ADHD. METHODS: This 8 week, multicentre, open-label study randomized 147 subjects to either once-daily OROS-MPH or usual care with IR-MPH. Subjects were titrated to a clinically effective dose of either study medication over 4 weeks and maintained on that dose for an additional 4 weeks. The SNAP-IV parent-rating scale was used to assess effectiveness. RESULTS: OROS-MPH showed statistically significant superiority to IR-MPH in remission rate based on the 18 ADHD symptoms (p=0.0002, X2=13.8, df=1) and severity of ADHD and ODD symptoms (p=0.004, F=8.4, df=1,127), as well as on the following secondary assessments: IOWA Conners, Conners Parent Rating Scale (short version), Parent Stress Index, (short version); Visual Analogue Scale for social play; Clinical Global Impression-Severity, Clinical Global Impression-Improvement and Parent Satisfaction with treatment. OROS-MPH and IR-MPH were both well tolerated with a similar side effect profile. CONCLUSIONS: Once-daily OROS-MPH is significantly more effective than usual care with IR-MPH based on multiple outcome measures including remission rate.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
