Delivery of progestins via the subdermal versus the intrauterine route: comparison of the pharmacology and clinical outcomes
Bibliographic record
Abstract
INTRODUCTION: Subdermal and intrauterine progestin releasing systems are two types of long-acting reversible contraceptive systems (LARC). Their use has transformed current contraceptive practice management. There is not much objective evidence to help decide which method is preferable and in which particular circumstance using objective criteria. AREAS COVERED: MEDLINE, POPLINE, PubMed, and clinicaltrials.gov were searched using the terms "implant" vs "IUS" and then adding the terms "levonorgestrel" and "etonogestrel" to the implant arm and "levonorgestrel" to the IUS arm. This was done using commercial names as well for the terms "pharmacodynamics" and "pharmacokinetics" as well as for the term "therapeutic." Preference was given to comparative studies of the highest degree. EXPERT OPINION: Under normal circumstances, user satisfaction appeared marginally greater for intrauterine rather than subdermal progestin provision. However, after uterine events such as pregnancy or surgical evacuation of the uterus, implants performed better. Intrauterine progestin is preferable for therapeutic purposes.

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.
