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
Background: Adenomyosis is characterized by ectopic endometrial tissue, which causes dysmenorrhea, menstruation, and infertility, significantly impairing quality of life. Current treatments-including medications, surgery, and interventional methods-all have limitations. Cryoablation, a technique that induces tissue necrosis through ultra-low temperature exposure followed by rapid thawing, has demonstrated efficacy in treating solid tumors (e.g., liver and kidney cancer). However, its application in adenomyosis remains in the exploratory phase. This study aims to evaluate the feasibility and efficacy of ultrasound (US)-guided percutaneous cryoablation for adenomyosis. Methods: A retrospective study was conducted on symptomatic adenomyosis patients seeking uterine and fertility preservation who underwent US-guided percutaneous cryoablation at the Shengjing Hospital of China Medical University from January 2024 to September 2024. Follow-up assessments were conducted at 1, 3, and 6 months postoperatively. Dysmenorrhea severity was evaluated using the Visual Analogue Scale (VAS). The quality of life was quantified using the Uterine Fibroid Symptom and Quality of Life Questionnaire (UFS-QOL) score. Treatment efficacy was assessed based on changes in uterine volume and lesion volume measured by US. Intraoperative and postoperative complications were recorded to evaluate safety. Results: A total of 8 patients with adenomyosis underwent cryoablation under local anesthesia. The median VAS score was 8.5 [interquartile range (IQR), 7.75-9] postoperatively, 5.5 (IQR, 4.75-6; P<0.05) at 1 month, 4 (IQR, 4-4; P<0.05) at 3 months, and 3 (IQR, 2.75-3.25; P<0.05) at 6 months. Six months postoperatively, the median UFS-QOL score decreased from 132 (IQR, 121.5-138) preoperatively to 93 (IQR, 87.5-98, P<0.05). US revealed a 68% uterine volume reduction from 334.89 cm Conclusions: US-guided percutaneous cryoablation under local anesthesia is safe and effective in the short-term follow-up for treating adenomyosis, offering a promising uterine-sparing alternative for symptomatic patients.
