The analytic flow plan for identifying metabolites associated with CKD etiology. The flow of the analytic approach used to identify individual metabolites associated with each CKD cause. Lasso generated panels of metabolites for subsequent analysis while accounting for metabolite and clinical covariate multicollinearity. Second-pass ML classifiers additionally accounted for dimensionality and multicollinearity among the Lasso-selected metabolites.
