Referee report. For: Are evidence-based vasectomy surgical techniques performed in low-resource countries? [version 1; peer review: 2 approved]
Bibliographic record
Abstract
Background: Research evidence published 10 to 15 years ago has shown that the type of vasectomy surgical technique performed can influence the effectiveness and the safety of the procedure. The objective of this study was to determine if evidence-based vasectomy surgical techniques are integrated in the vasectomy programs of selected low-resource countries. Methods: The surgical techniques recommended to perform the two steps of the vasectomy procedure (isolation/exposition and occlusion of the vas deferens) were extracted from current evidence-based clinical practice guidelines. Documents describing male sterilisation standards and practice from Kenya, Rwanda, India, Nepal, Mexico, Honduras, Colombia and Haiti were reviewed to assess adequacy with international guideline recommendations. Results: Best recommended techniques are 1) a minimally invasive technique including the no-scalpel technique (known as the no-scalpel vasectomy (NSV)) to isolate and expose the vas deferens, and 2) cautery of the mucosa of the vas preferably combined with interposition of the fascia (FI) to occlude the vas deferens. The NSV is largely adopted and performed to isolate the vas in selected low-resources countries. Ligation and excision (LE) of a small segment of the vas deferens combined with FI is the most common vas occlusion technique mentioned in the country standards. Cautery as recommended in the guidelines is seldom used in selected countries. Conclusions: Effective and adapted vasectomy vas occlusion techniques are available, but are still underused in many low-resource countries. Providing the most effective vasectomy surgical techniques increases users’ confidence and satisfaction regarding male sterilization and may lead to higher acceptability and uptake.

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.
