Abstract
Two strategies to manage symptom re-emergence due to wearing-off with conventional levodopa/dopa-decarboxylase inhibitor (DDCI) therapy were compared in patients with Parkinson's disease (PD) in this randomized, open-label trial. PD patients receiving 3 daily doses of levodopa/DDCI were randomized to either levodopa/DDCI and entacapone or an increased dose frequency of levodopa/DDCI with or without an increased total daily dose (dose fractionation). After 1 month of treatment, patients were followed up for 1 year. A greater proportion of levodopa/DDCI and entacapone-treated patients had treatment success compared with dose-fractionated patients, according to investigator Clinical Global Impression of Change scores at 1 month (68 vs. 59%, respectively) and 1 year (60 vs. 51%, respectively). Mean 'off' time (time with symptoms) was improved in both groups at 1 month and 1 year, despite a reduction in the mean daily levodopa dose in the levodopa/DDCI and entacapone group at 1 month. The mean daily levodopa dose was increased in the dose fractionation group. At 1 month, there was a 4% reduction in patients experiencing dyskinesia with levodopa/DDCI and entacapone and a 3% increase with dose fractionation. These data suggest that levodopa/DDCI and entacapone reduces time with symptoms, the rate of motor complications and the daily levodopa dose compared with dose fractionation. However, as the observed differences were not statistically significant, further studies are required to confirm these results.

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
