The predicted value for venous thromboembolism based on a modified model of caprini combined with fasting blood glucose and D-dimer: a retrospective study.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe Caprini risk assessment model (RAM) is a classical score that evaluates the risk of developing venous thromboembolism (VTE) aimed at patients with lower extremity fractures (LEF). However, the influencing factors of RAM pay more attention to clinical characteristic variables and recognized thrombophilia markers such as prothrombin, while ignoring the influence of other laboratory indicators on thrombosis. This is the first paper to screen predictive risk factors associated with VTE to modify the Caprini model and determine its diagnostic value. RESULTS AND
methodsWe included 953 LEF patients from January 2019 to December 2021 and randomized them in a 7:3 ratio into a training set (n = 667) and a validation set (n = 286). Logistic regression and LASSO regression were used to screen for independent predictors of patients in the training set. Logistic regression screened for: age (OR 1.04, 95% CI 1.02-1.06), D-dimer (OR 1.06, 95% CI 1.03-1.08), Caprini (OR 1.17, 95% CI 1.08-1.27) and fasting blood glucose (FBG) (OR 1.18, 95% CI 1.03-1.35), which also appeared in the LASSO seven-factor model. In addition to Caprini and age, FBG and D-dimer may be important predictors of deep vein thrombosis in patients with LEF. Therefore, we constructed three models. caprini + D-dimer, caprini + FBG, and caprini + D-dimer + FBG. We compared them with caprini alone. Caprini + FBG + D-dimer showed the greatest ROC (0.784, 95% CI 0.730-0.837, Delong test P = 0.002 vs. Caprini's ROC). D-dimer and FBG have a significant increase in the predictive effect for predicting DVT in terms of NRI (59.98% improvement, P < 0.001) and IDI (9.55% improvement, P < 0.001), showing the best net benefit for predicting DVT when the threshold probability was between 27 and 91%.
conclusionsCaprini RAM combined with D-dimer and FBG can improve the diagnostic efficiency of Caprini alone and provide a new method to better predict the risk of VTE in LEF patients.
