Venous Thromboembolism After Coronary Artery Bypass Increases Health Care Costs: A Propensity Score-Matched Analysis.
Article in The Annals of thoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundVenous thromboembolism (VTE) after cardiac surgery is rare but may increase hospital resource utilization. We sought to determine the cost associated with development of VTE in patients undergoing isolated coronary artery bypass grafting (CABG).
methodsThe Society of Thoracic Surgeons data were identified for all patients undergoing isolated CABG between 2010 and 2020. VTE was defined as any deep venous thrombosis or pulmonary embolism occurring in-hospital during the index operation. Patients were propensity score matched by optimal full matching with threshold standard mean difference between -0.1 and 0.1. Cost analysis was performed on matched groups with a weighted linear regression model. A marginal effects analysis was used to determine total hospital costs.
resultsWe analyzed 18,159 patients, including 162 (0.9%) in whom VTE developed. Weighted linear regression found that VTE increased total index hospitalization cost by an average of $23,150 (P < .001), driven mostly by increases in intensive care unit expenditure ($12,640), pharmacy costs ($4649), and then step-down unit costs ($1719). The average inpatient hospital cost for a patient with VTE was $57,577 compared with $34,010 for those without VTE. This increased per-patient cost equated to approximately $3.8 million more for all patients with VTE after CABG during the study period.
conclusionsDevelopment of VTE after isolated CABG is associated with a significant increase in health care resource utilization driven by increased intensive care unit, pharmacy, and step-down unit costs. Centers without appropriate prophylaxis protocols should consider implementing one to best prevent this increase in resource utilization from development of this complication.
