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] Design: randomised controlled equivalence trial. ### ![Graphic][4] Allocation: {concealed*}†. ### ![Graphic][5] Blinding: blinded (data collectors, outcome assessors, and data analysts).* ### ![Graphic][6] Follow up period: 3 years. ### ![Graphic][7] Setting: practices of 50 family practitioners in Kingston, Ontario, Canada. ### ![Graphic][8] 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. Exclusion criteria: pregnancy, hypertension follow up by a specialist, or opinion of family practitioner that patient could not be randomised to 6 month follow up because of other medical problems. ### ![Graphic][9] Intervention: 3 month (n = 302) or 6 month (n = 307) follow up of … [1]: {openurl}?query=rft.jtitle%253DBMJ%26rft_id%253Dinfo%253Adoi%252F10.1136%252Fbmj.37967.374063.EE%26rft_id%253Dinfo%253Apmid%252F14726370%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=bmj&resid=328/7433/204&atom=%2Febmed%2F9%2F5%2F138.atom [3]: /embed/inline-graphic-1.gif [4]: /embed/inline-graphic-2.gif [5]: /embed/inline-graphic-3.gif [6]: /embed/inline-graphic-4.gif [7]: /embed/inline-graphic-5.gif [8]: /embed/inline-graphic-6.gif [9]: /embed/inline-graphic-7.gif

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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
