A Proposed Statistical Approach for Conducting Longitudinal Assessment of Circulating Tumor DNA

Christopher R. Pretz, Jiemin Liao, Caroline M. Weipert…·Amar K. Das

This paper proposes a statistical framework using hierarchical mixed-effects models to analyze ctDNA dynamics in liquid biopsy data, finding that a hierarchical linear spline model best captures patient-level ctDNA evolution.
