Platelet-to-lymphocyte ratio as a predictor of preoperative venous thrombosis in femoral fracture patients: a retrospective cohort study

PLR is an independent risk factor for lower extremity DVT in patients with femoral fracture, with a modest predictive performance (AUC = 0.60) that slightly outperforms age and NLR in this cohort. While these findings suggest PLR may have potential as a supplementary biomarker for DVT risk stratification, its clinical utility requires further validation in larger, multicenter studies.
