Response to Letter to the Editor: Prospective Validation of PaDd—A Roadmap

To the Editor: We thank Dr Vijayasimha and colleagues for their thoughtful analysis of our work and their proposal for prospective validation of the Padua × D-dimer (PaDd) score. Their roadmap provides a rigorous framework that addresses critical gaps in our single-center retrospective design. We welcome this opportunity to clarify key methodological considerations and invite the global research community to collaborate on next-generation studies.
