Efficacy of Fertility-Sparing Treatment With Progestin Is Associated With Different Molecular Classification in Endometrial Carcinoma and Atypical Endometrial Hyperplasia.
Article in Cancer medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo investigate the impact of various molecular characteristics on the outcomes of fertility-preserving therapy in patients with endometrial cancer (EC) and atypical endometrial hyperplasia (AEH).
methodsA total of 14 EC cases and 60 AEH cases were retrospectively analyzed at the Women's Hospital, Zhejiang University from January 2013 to October 2022.
resultsThis study investigated the molecular profiles and outcomes of fertility preservation in 74 cases. The most prevalent molecular profile was NSMP type (63.9%), followed by p53abn type (21.3%) and MMRd type (14.8%). After 6 months of progesterone therapy, the cumulative CR rates were 100% for NSMP type, 83.3% for MMRd type, and 33.3% for p53abn type (p = 0.006). The CR rate in the p53abn group was significantly lower than in the other two groups (p = 0.006), with a notably higher recurrence rate (p = 0.006). ER and PR expression was significantly lower in the MMRd and p53abn groups (p = 0.002). A total of 26 pregnancies (42.6%) were observed. In the EC group, the pregnancy rate of p53abn was lower than that of the NSMP group (0% vs. 83.3%, p = 0.02). In the AEH group, pregnancy rates of p53abn and MMRd were not significantly different from the NSMP group (0% vs. 50%, p = 0.16; 33.3% vs. 50%, p = 0.20).
conclusionMolecular classification may serve as a predictive tool for the efficacy of fertility preservation therapy in patients with EC and AEH and was found to be particularly useful for identifying p53 mutants, which are associated with a high risk of recurrence, as well as MMRd types, which are known to lead to poor responses to progesterone treatment.
