Ectocervical margin involvement is associated with postoperative hrHPV positivity after hysterectomy or residual cervix resection for incompletely excised CIN3: a retrospective study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPersistent high-risk human papillomavirus (hrHPV) infection after hysterectomy or residual cervix resection for incompletely excised cervical intraepithelial neoplasia grade 3 (CIN3) remains a clinical concern. However, the factors associated with postoperative hrHPV positivity in this setting are not well characterized.
methodsThis retrospective study included 288 patients who were treated between 2014 and 2024. We evaluated factors associated with postoperative hrHPV positivity after hysterectomy or residual cervix resection for incompletely excised CIN3. Patients were grouped according to their hrHPV status at the first postoperative follow-up, and associated factors were identified by using logistic regression.
resultsAt the first postoperative follow-up, 50 patients (17.4%) were hrHPV positive. According to the univariate analysis, postoperative hrHPV positivity was associated with ectocervical margin involvement, older age, and lower gravidity (all p < 0.05). Multivariate analysis revealed that ectocervical margin involvement remained independently associated with postoperative hrHPV positivity (OR 5.273, 95% CI 1.491-18.640; p = 0.010). For the patients who were hrHPV positive at the first postoperative follow-up, subsequent clearance of infection mostly occurred within 2 years after surgery.
conclusionsEctocervical margin involvement was associated with a higher likelihood hrHPV positivity at the first follow-up after hysterectomy or residual cervix resection for incompletely excised CIN3. This observation warrants confirmation in future prospective studies.
