Association between D-dimer difference and risk of postoperative venous thromboembolism in endometrial cancer: a retrospective cohort study.
Article in Thrombosis journal, 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
objectiveTo investigate the association between D-dimer level changes and venous thromboembolism (VTE) risk in endometrial cancer patients undergoing surgery.
methodsThis retrospective cohort study included 307 endometrial cancer patients who underwent surgical treatment at Fujian Maternity and Child Health Hospital between January 2022 and December 2024, with follow-up to December 2025. D-dimer change was the exposure variable and VTE occurrence the outcome. Multivariable logistic regression assessed independent effects after adjusting for 17 covariates, including age, body mass index, FIGO stage, and comorbidities. Threshold effect and stratified analyses were conducted.
resultsEach one-unit increase in D-dimer change was significantly associated with higher VTE risk (adjusted OR = 1.202; 95% CI: 1.076-1.342; P = 0.001). Nonlinear testing revealed a significant threshold effect (P < 0.001) at 3.78: below this threshold, VTE risk increased sharply (OR = 7.761; 95% CI: 4.286-14.051); above it, risk declined (OR = 0.643; 95% CI: 0.526-0.785). Mediation analysis showed anticoagulant therapy, infection, and caprinin had negligible mediating effects (proportion < 0.2%; P > 0.86).
conclusionD-dimer level changes exhibit a nonlinear association with postoperative VTE risk, characterized by a distinct threshold effect. These hypothesis-generating findings suggest that monitoring D-dimer trajectories rather than absolute values may offer a novel dimension for perioperative VTE risk stratification, warranting prospective validation in multicenter cohorts before clinical application.
