    Composite quantile regression approach to batch effect correction in microbiome data by Jiwon Park, Taesung Park

    Published 2025-02-01
    “…Additionally, to handle nonsystematic batch effects, we employ composite quantile regression. By adjusting the distribution of OTUs to be similar based on a reference batch selected using the Kruskal-Walis test method, we consider the variability at the OTU level.ResultsThe performance of the model is evaluated and compared with existing methods using PERMANOVA R-squared values, Principal Coordinates Analysis (PCoA) plots and Average Silhouette Coefficient calculated with diverse distance-based metrics. …”

    A composite measurement concept for monitoring cardiac function in Fabry disease by Pooja Nandi, Robert Ellis, Jennifer Hiros, Paul Howard, Biliana O. Veleva-Rotse

    Published 2025-07-01
    “…The clinician advisory board noted a lack of specific diagnostic, monitoring, and prognosis (especially cardiac) tools in FD. The composite measurement concept was developed to capture the signs and symptoms most important to people living with FD, alongside heart-rate variability, electrocardiograms, blood pressure, and quality of life as relevant measures within the cardiac domain that can be staged in a progression model with clear group boundaries. …”
