Significance of ovarian transposition in the preservation of ovarian function for young cervical cancer patients undergoing postoperative volumetric modulated radiotherapy.
Article in Annals of translational medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundThis paper aimed to evaluate the effectiveness of ovarian transposition (OT) and the dose constraint for preserving ovarian function in young cervical cancer patients who underwent postoperative volumetric modulated arc therapy (VMAT).
methodsA retrospective analysis was conducted of young cervical cancer patients who accepted postoperative VMAT in the Affiliated Cancer Hospital of Nanjing Medical University from September 2015 to September 2018. VMAT plans for OT and non-OT patients were compared, and the patients' ovarian function was followed up. The transposed position of the ovaries and the radiation dose constraint were further explored using a receiver operator characteristic (ROC) curve.
resultsA total of 51 young patients (age ≤40 years) were included in the study, 32 of whom underwent OT and 19 of whom did not. For these OT and non-OT patients, the homogeneity index (HI), conformity index (CI), organs at risk (OARs), average number of monitor units (MUs), and mean treatment time were similar and showed no statistically significant difference (P≥0.05). Through follow-up studies, the number of patients with preserved ovarian function was found to be 22 (out of 32) and 0 (out of 19) in the OT and non-OT patients, respectively. The minimal distance for preserving ovarian function was determined as 2.1 cm between the center of a transposed ovary and the planning target volume (PTV) margin. The optimal limited radiation doses were estimated as maximum dose (D
conclusionsOT shows no negative effects on dose distribution, target region conformity, protection of OARs, or treatment efficacy and is therefore a reliable method in the preservation of ovarian function for young cervical cancer patients undergoing postoperative radiotherapy using the VMAT technique. Specifically, when the distance between the center of a transposed ovary and the PTV margin is more than 2.1 cm, and the radiation dose is limited to a D
