Endometrial hyperplastic changes as an independent predictor of recurrence after hysteroscopic polypectomy: a retrospective cohort 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
objectiveTo identify risk factors for recurrence after hysteroscopic endometrial polypectomy, with particular emphasis on postoperative pathological features (endometrial hyperplastic changes) and potential protective role of medical therapy using progestins.
methodsThis retrospective cohort study included 145 patients who underwent hysteroscopic polypectomy at XianJu People's Hospital from January 2020 to December 2023. Data on demographics, polyp characteristics (number, size), postoperative pathology (presence of hyperplastic changes), and postoperative progestin therapy were collected. The primary outcome was polyp recurrence, defined as a new lesion confirmed by ultrasound or hysteroscopy at least six months after surgery. Survival analysis using the Kaplan-Meier method and Cox proportional hazards regression were performed to screen for independent risk factors.
resultsThe mean follow-up time was 24.28 months. Recurrence occurred in 57 of 145 patients (39.3%). Multivariate Cox regression analysis identified endometrial hyperplastic changes as a significant independent risk factor for recurrence (HR = 2.016, 95% CI: 1.199-3.389,
conclusionEndometrial hyperplastic changes in postoperative pathology are a key independent predictor of polyp recurrence after hysteroscopic polypectomy, nearly doubling the risk. While progestin therapy did not show a statistically significant protective effect, the observed trend toward risk reduction is clinically meaningful. Postoperative pathological findings should be used for risk stratification, and intensified follow-up should be considered for high-risk patients.
