No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

CALM-PD (Comparison of the agonist pramipexole with levodopa on motor complications of Parkinson's disease) is a randomized, multicenter, double-blind, controlled clinical trial designed to compare the policy of initial treatment of pramipexole with the policy of initial treatment with levodopa in early, symptomatic Parkinson's disease with regard to the development of dopaminergic motor complications. At 22 American and Canadian sites, 301 eligible subjects requiring antiparkinsonian therapy to treat emerging disability were enrolled in CALM-PD and randomized to (i) active pramipexole and placebo levodopa or (ii) placebo pramipexole and active levodopa. Subjects are being evaluated systematically at regular intervals during a 23.5-month period to determine if and when dopaminergic motor complications (wearing off, dyskinesias, "on-off" effects) occur. In addition, quality-of-life outcomes, economic outcomes, and functional imaging outcomes are being assessed in standard fashion with [123I] beta-CIT and SPECT imaging throughout the trial. The study design contains many provisions to approximate routine clinical practice and to produce data about clinical effectiveness, tolerability, and cost to facilitate the evidence-based practice of neurology.

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.
