Table 2 Multivariate logistic regression for risk of deep vein thrombosis, pulmonary embolism, and all-cause venous thromboembolic disease among primary total knee arthroplasty, unicompartmental knee arthroplasty, and revision total knee arthroplasty

From: Unicompartmental knee arthroplasty and revision total knee arthroplasty have a lower risk of venous thromboembolism disease at 30 days than primary total knee arthroplasty
