Validation of the BPro radial pulse waveform acquisition device in pregnancy and gestational hypertensive disorders
Bibliographic record
Abstract
OBJECTIVE: To validate the BPro blood pressure (BP) wrist device for use in pregnancy and preeclampsia according to the Universal Standard protocol. PARTICIPANTS AND METHODS: BP was measured sequentially in 45 pregnant women (including 15 with preeclampsia, 15 with gestational hypertension and 15 who remained normotensive) alternating between a mercury sphygmomanometer and BPro device. RESULTS: The BPro is accurate in pregnancy with a mean device-observer difference of -1.7 ± 6.1 and 0.1 ± 4.6 mmHg for SBP and DBP, respectively. In women with preeclampsia, BPro also met the validation criteria for the Universal Standard protocol with a mean device-observer difference of -2.7 ± 7.1 and 0.3 ± 4.7 mmHg for SBP and DBP, respectively. However, the number of absolute BP differences within 5 mmHg was considerably fewer in those with preeclampsia when compared to the other two subgroups. CONCLUSION: The BPro device can be recommended for BP measurement in pregnancy but should be used with caution in those with confirmed preeclampsia.

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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
