A nomogram for the prediction of endometrial cancer in postmenopausal women with a thickened endometrium.
Article in BMC women's health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe aim of this study was to develop a nomogram model for predicting the occurrence of endometrial cancer (EC) in postmenopausal women with a thickened endometrium.
methodsThe clinical data of postmenopausal women with endometrial thickening who were diagnosed via transvaginal ultrasound and who underwent hysteroscopic endometrial pathology examinations at the Obstetrics and Gynecology Department of Xuanwu Hospital, Capital Medical University, were retrospectively collected from January 2018 to March 2023. Univariate and multivariate logistic regression analyses were carried out to determine the independent risk factors for the development of EC in postmenopausal women with a thickened endometrium. We subsequently constructed a predictive nomogram model for the risk of developing EC in postmenopausal women with endometrial thickening by including significant independent risk factors for the development of EC. Additionally, internal and external validation were performed to evaluate the EC prediction model.
resultsIn total, 550 postmenopausal women with a thickened endometrium were included in this study. Older age (odds ratio [OR]: 1.06, 95% confidence interval [CI]: 1.01-1.12, P = 0.02), postmenopausal bleeding (OR: 12.34, 95% CI: 4.44-34.30, P < 0.01), history of irregular menstruation (OR: 19.20, 95% CI: 1.94-190.43, P = 0.01), greater endometrial thickness (ET) (OR: 5.03, 95% CI: 2.45-10.32, P < 0.01), and the presence of polypoid mass-like lesions (OR: 30.33, 95% CI: 8.97-102.51, P < 0.01) were identified as independent risk factors associated with the occurrence of EC. A nomogram was established according to the abovementioned independent risk factors, with satisfactory discrimination being observed in the training set (AUC: 0.897, 95% CI: 0.858-0.935) and in the validation set (AUC: 0.941, 95% CI: 0.886-0.996). The calibration plots indicated favorable agreement between the predictions of the nomogram model and the actual observations in both the training and validation sets. Furthermore, decision curve analysis indicated that the nomogram model was clinically useful and had good discriminative ability.
conclusionsIn this study, we established a predictive nomogram model for the risk of developing EC that will help clinical physicians in developing more accurate and personalized diagnostic and treatment strategies for postmenopausal women with a thickened endometrium. Future multicenter studies are still needed in the future to increase the universality of prediction models.
