Abstract
Birtwhistle RV, Godwin MS, Delva MD, et al. Randomised equivalence trial comparing three month and six month follow up of patients with hypertension by family practitioners. BMJ 2004;328:204–9. [OpenUrl][1][Abstract/FREE Full Text][2] Q In patients with hypertension, are 3 monthly and 6 monthly scheduled follow ups by family practitioners equivalent in blood pressure (BP) control, treatment compliance, and patient satisfaction? Clinical impact ratings GP/FP/Primary care ★★★★★★☆ ### ![Graphic][3]</img>Design: randomised controlled equivalence trial. ### ![Graphic][4]</img>Allocation: {concealed*}†. ### ![Graphic][5]</img>Blinding: blinded (data collectors, outcome assessors, and data analysts).* ### ![Graphic][6]</img>Follow up period: 3 years. ### ![Graphic][7]</img>Setting: practices of 50 family practitioners in Kingston, Ontario, Canada. ### ![Graphic][8]</img>Patients: 614 patients who were 30–74 years of age with a diagnosis of essential hypertension, were taking ⩾1 antihypertensive drug, and had controlled BP (<140/90 mm Hg in patients ⩽40 y, <150/95 mm Hg in patients 41–59 y, and <160/95 mm Hg in patients ⩾60 y) for ⩾3 months before study entry.

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 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 itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
The models disagree on parts of this classification; every voice is preserved in the section at the end of the page.
