Cross‐validated receiver operating curves of the relationship of the 6 significant plasma LPC species with the highest quartile of k _PCr using Super Learner, cross‐validated (CV) Super Learner, and eight machine‐learning algorithms. BAGGed CART, bootstrap aggregated classification and regression tree; CV, cross‐validated; LASSO, least absolute shrinkage and selection operator; GBM, generalized boosted regression; GLM, generalized linear model (i.e., main effects logistic regression); MARS, multivariate adaptive regression splines
