Correlation of cervical cytology and visual inspection with acetic acid in HIV-positive women
Bibliographic record
Abstract
The prevalence of squamous intraepithelial lesion is higher among human immunodeficiency virus (HIV)-positive women. These lesions when they occur in these patients are also more difficult to treat. A total of 205 consenting HIV-seropositive women were recruited. A cervical cytology (Pap smear) was taken, followed by visual inspection with freshly prepared 5% acetic acid and cervical biopsy taken from the squamocolumnar junction as the reference for diagnosis to avoid verification bias. The sensitivity of VIA was 76.0% (95% CI 52.0-91.0); specificity 83.0% (95% CI 77.0-88.0); positive predictive value 34.0% (95% CI 21.0-49.0). The sensitivity of cervical cytology (Pap smear) was 57.0% (95% CI 34.0-77.0), specificity of 95.0% (95% CI 90.0-97.0), and positive predictive value of 55.0% (95% CI 33.0-75.0). In HIV-seropositive women, the sensitivity of VIA is 76.0%, making it a useful screening test for preinvasive lesion of the cervix in low resource settings.

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.
