Cover Story: Longitudinal stability of untargeted plasma and cerebrospinal fluid (CSF) metabolites was assessed using samples from participants enrolled in the Wisconsin Registry for Alzheimer’s Prevention (WRAP) and the Wisconsin Alzheimer’s Disease Research Center (ADRC) studies. To identify metabolites most suitable for longitudinal analysis, we developed a composite score that integrates within- and between-batch reliability with measures of technical variance, highlighting metabolites that are temporally stable and robust to batch effects. This composite score is readily applicable to other longitudinal or multi-batch metabolomic datasets, where it can be used retrospectively to evaluate the reliability of key findings or prospectively to prioritize stable metabolites, thereby supporting more informed study design and interpretation. View this paper
