Prevalence and clinical burden of venous thromboembolic events (VTEs) in contemporary total knee arthroplasties (TKAs) in US hospitals.

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
Introduction: Total knee arthroplasty (TKA) is a highly demanded procedure in orthopedic surgery, with over 1.3 million joint arthroplasties performed annually in the U.S. The increasing need for TKAs is driven by an aging population, rising obesity rates, and advances in surgical techniques. Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), significantly impacts TKA patients' mortality and morbidity. Despite advances in prophylaxis and Enhanced Recovery After Surgery (ERAS) protocols reducing VTE incidence, survival rates have not markedly improved. This study aims to identify preoperative predictors of PE and DVT in TKA patients and examine their impact on hospital stays and mortality. Methods: A retrospective observational study was conducted using data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database, focusing on 367,365 TKA patients from 2016 to 2021. Preoperative variables, including demographic factors, comorbidities, and functional status, were analyzed. Primary endpoints were PE and DVT predictors; secondary endpoints included 30-day mortality and prolonged hospital stay. Univariate and logistic regression analyses were performed using SPSS version 26. Results: Univariate analysis revealed significant associations of male gender, older age, Hispanic ethnicity, smoking, dyspnea, CHF, and COPD with DVT and PE. Multivariate analysis confirmed female sex, younger age, Hispanic ethnicity, and COPD as independent DVT predictors, and independent functional status, smoking, COPD, CHF, and metastatic malignancy as PE predictors. VTE prevalence was 1.09 % (0.67 % DVT, 0.42 % PE), with PE associated with higher mortality (0.78 %) and prolonged hospital stays. Conclusion: Demographic and clinical variables significantly influence VTE risk post-TKA. Tailored interventions and comprehensive preoperative assessments are crucial for optimizing patient outcomes and reducing thrombotic risks.
