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 compare surgical and oncologic outcomes between conventional resectoscopic surgery and mechanical hysteroscopic tissue removal (mHTR) systems in high-risk patients not suitable for standard surgery undergoing conservative treatment for multifocal endometrial atypical hyperplasia/endometrial intraepithelial neoplasia (EAH/EIN) or early-stage low-grade endometrioid endometrial cancer (EEC).
methodsWe conducted a single-center, retrospective cohort study at the Department of Gynecology and Physiopathology of Human Reproduction, S. Orsola-Malpighi Hospital, University of Bologna, Italy. A total of 31 high-surgical-risk patients with EAH/EIN or early-stage low-grade EEC were included: 18 underwent conventional resectoscopic endo-myometrial resection, while 13 were treated with mHTR systems. All patients received a levonorgestrel-releasing intrauterine device (LNG-IUD) postoperatively. After treatment, patients underwent an 18-month follow up with endometrial biopsies every 6 months.
resultsThe mHTR group had significantly shorter operative times (mean 12.3 ± 7.7 min) compared with the resectoscopic surgery group (mean 40.6 ± 11.8 min, P < 0.001). Additionally, the incidence of intrauterine adhesions was lower in the mHTR group (P < 0.001). There were no significant differences between the two groups in terms of disease presence at 6, 12, or 18 months.
conclusionsHysteroscopic endo-myometrial resection, with resectoscopic technique or with mHTR systems, combined with LNG-IUD may represent a safe alternative for patients at high surgical risk with EAH/EIN or early-stage low-grade EEC. Moreover, mHTR demonstrated advantages such as shorter operative times and fewer adhesions. A large multicenter prospective study is needed to confirm our study findings.
