Serum neurofilament light chain as a biomarker of inflammatory activity in relapsing-remitting multiple sclerosis: a real-world longitudinal cohort study
Abstract Objectives Serum neurofilament light chain (sNfL) reflects neuroaxonal injury in relapsing-remitting multiple sclerosis (RRMS), but its clinical utility is limited by high interindividual variability and confounders such as renal function. Population-based thresholds may therefore be suboptimal for longitudina...
