Risk Factors for the Development of Hospital-Acquired Pediatric Venous Thromboembolism: Dealing With Potentially Causal and Confounding Risk Factors Using Directed Acyclic Graph (Dag) Analysis
Abstract:Introduction: Hospital-acquired venous thromboembolism (HA-VTE) in children comprises multiple risk factors that should not be evaluated separately due to collinearity and multiple cause and effect relationships. This is one of the first case-control study of pediatric HA-VTE risk factors using Directed Acyclic Graph (DAG) analysis (figure 1).
Material and Methods: Retrospective, case-control study with 22 cases of objectively confirmed HA-VTE and 76 controls matched by age, sex, unit of admission, and period … Show more
