An interpretable delta ultrasound radiomics model for predicting live birth outcomes in single vitrified-warmed blastocyst transfer.
Article in Journal of ovarian research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 develop and validate an interpretable delta ultrasound radiomics model for predicting live birth following single vitrified-warmed blastocyst transfer (SVBT).
designRetrospective cohort study.
settingThe First Affiliated Hospital of Guangxi Medical University. PATIENTS: 528 infertile women who underwent SVBT between January 2019 and December 2022.
interventionDelta radiomics analysis of the gestational sac at 6th and 8th weeks' gestation, with extraction of radiomic features and integration with clinical parameters.
main outcome measuresLive birth, defined as the delivery of a single infant at ≥28 weeks of gestation. Radiomic feature differences between weeks 6 and 8 (delta features), combined with maternal age, were used to build ten machine learning models. The best-performing model was interpreted using SHapley Additive exPlanations (SHAP).
resultsA delta radiomics model based on logistic regression yielded superior predictive performance compared to models using only single-timepoint features, achieving an AUC of 0.883 in the training cohort. Incorporating maternal age resulted in an AUC of 0.747 in the testing cohort. SHAP analysis confirmed that both delta radiomic features (from weeks 6 and 8) and maternal age substantially influenced model predictions.
conclusionThe Delta ultrasound radiomics model with SHAP-based interpretability offers a comprehensive and dynamic approach for predicting live birth in SVBT.
trial registrationNot applicable. CAPSULE: A delta ultrasound radiomics model incorporating 6 and 8 week gestational sac features, combined with clinical factors, improves live birth prediction following SVBT.
