Propensity Score Matching

Fillmore has utilized propensity score matching to minimize selection bias and control for confounding variables in retrospective cohort studies. Through this methodology, he has evaluated the comparative effectiveness of therapeutic interventions, including the neuroprotective potential of tumor necrosis factor inhibitors in patients with rheumatoid arthritis and the survival advantages of specific anticoagulant regimens in cancer-associated venous thromboembolism. His work demonstrates the utility of this approach in deriving robust clinical insights from large healthcare databases.
