The Improved-EFI Score: A Multi-Omics-Based Novel Efficacy Predictive Tool for Predicting the Natural Fertility of Endometriosis Patients.
Article in International journal of general medicine, 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
Objective: Infertility caused by endometriosis (EM) directly affects the possibility of pregnancy in women of gestational age. This study aims to establish a prediction model to accurately predict the natural pregnancy outcome of patients with EM, providing valuable information for clinical decision-making. Methods: We retrospectively selected a total of 496 patients who underwent their first laparoscopic surgery for infertility at the Obstetrics and Gynecology Department of Jingzhou Central Hospital from January 2016 to June 2023. An improved endometriosis fertility index (EFI) predictive model was created based on ultrasound radiomics and urinary proteomics gathered during the patient's initial admission, using two machine learning algorithms. The predictive model was evaluated for C-index, calibration, and clinical applicability through receiver working characteristic curve, decision curve analysis. Results: The improved EFI prediction model nomogram, based on five ultrasound radiomics parameters and three urine proteomics, had AUC values of 0.921 (95% CI: 0.864-0.978) and 0.909 (95% CI: 0.852-0.966) in the training and validation sets, respectively, while the traditional EFI prediction model had AUC values of 0.889 (95% CI: 0.832-0.946) and 0.873 (95% CI: 0.816-0.930) in the training and validation sets, respectively. Additionally, the nomogram exhibited better discrimination ability and achieved an overall better benefit against threshold probability than the EFI model and decision tree in the decision curve analysis (DCA). Conclusion: The combined ultrasound radiomics-urine proteomics model was better able to predict natural pregnancy-associated patients with EM compared to the classical EFI score. This can help clinicians better predict an individual patient's risk of natural pregnancy following a first-ever laparoscopic surgery and facilitate earlier diagnosis and treatment.
