Development and validation of a preoperative nomogram for predicting venous thromboembolism risk after gynecologic oncology surgery.
Article in Discover oncology, 2026. 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
objectiveDevelop a nomogram to predict postoperative venous thromboembolism (VTE) risk in gynecologic malignancy patients.
methodsThis study retrospectively examined 2020 patients with gynaecological malignancies of Fujian Provincial Hospital and Fujian Provincial Hospital South Branch (Jinshan Hospital). Independent VTE predictors were identified via least absolute shrinkage and selection operator(LASSO) regression analysis and multivariate regression.A nomogram was constructed and validated. Performance was assessed using AUC, calibration curves, and decision curve analysis (DCA).
resultsThe predictive nomogram model consists of the following six factors: Triglyceride, Arrhythmia, Varicose vein, Hypoproteinemia, History of VTE, Tumor types.The resulting model showed good predictive performance in the derivation group (AUC 0.804, 95% CI 0.760-0.848) and in the validation group(AUC 0.824, 95% CI 0.760-0.887).The calibration curve showed that predictive nomogram had good consistency.The decision curve analysis revealed that within the probability threshold range of 5-80% (training group) and 10-70%(validation group), the predictive model yielded higher net benefits.
conclusionThe nomogram for predicting the risk of VTE after surgery for gynecological gynecologic malignancies demonstrated good identification accuracy and consistency. These predictors are easily accessible to clinicians, enabling them to individualize their assessment of patients.
