REGIONAL ANALGESIA Programmed Intermittent Epidural Bolus for Labor Analgesia During First Stage of Labor: A Sequential Allocation Trial to Determine the Effective Interval Time Between Boluses of a Fixed Volume of 2.5 mL of Bupivacaine 0.25% Plus Fentanyl 8 µg/mL

Abstract
( Can J Anaesth . 2021;68:653–660. doi: 10.1007/s12630-021-01922-6. Epub February 2, 2021) Programmed intermittent epidural bolus (PIEB) has been increasingly recommended and used during labor analgesia. This study aimed to determine the recommended time interval between boluses of 2.5 mL of bupivacaine 0.25% plus fentanyl 8 µ/mL to provide effective analgesia in 90% of pregnant women (EI90) during the first stage of labor.

How this classification was reachedexpand
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, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
