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
Objective: This study aims to investigate the effects of radiotherapy on ovarian function, endocrine function, and gut microbiota in cervical cancer patients who underwent ovarian transposition, compared to those who did not. Methods: This study included 100 cervical cancer patients treated from January to June 2024, divided into a control group (50 cases, radical surgery and radiotherapy) and an observation group (50 cases, ovarian transposition surgery plus radiotherapy). Radiotherapy protocols included conventional, intensity-modulated, or conformal radiotherapy, with 6MVX rays delivering 100-200 cGy per session, 5 sessions per week for 6 weeks. In the observation group, the ovarian region was shielded with a lead plate. Outcomes measured included ovarian and endocrine function, quality of life, adverse reactions, and gut microbiota composition. DNA was extracted from fecal samples for 16S rRNA sequencing and bioinformatics analysis, including α- and β-diversity, taxonomic composition, and LEfSe analysis. Results: Before radiotherapy, no significant differences in serum sex hormone levels were observed between the groups. After radiotherapy, the control group showed greater increases in FSH and LH and a more pronounced decrease in estradiol (E2) levels. Ovarian function preservation was significantly higher in the observation group (28.00% vs 0.00%). The observation group also had a higher Kupperman score 6 months post-surgery (28.01±10.22 vs 21.91±7.38). Adverse reaction rates were comparable. Gut microbiota analysis revealed differences in taxonomic composition, with higher Firmicutes (66.5% vs 65.56%) and Faecalibacterium (7.0% vs 2.7%) in the observation group, while Proteobacteria (4.1% vs 13.9%) and Shigella (2.7% vs 8.5%) were more abundant in the control group. LEfSe analysis identified notable species differences, including higher Peptoniphilus and Actinomyces in the observation group. Conclusion: Ovarian transposition surgery effectively preserves ovarian function in cervical cancer patients. Changes in gut microbiota during radiotherapy may influence endocrine outcomes, warranting further research.
