Analysis for acute kidney injury (AKI) stage. a PLS-DA scores plot of urine samples collected from patients who were AKI stages 0–1 (none-mild, circle) or stages 2–3 (moderate-severe, square, n = 10). Each circle and square represents a urine sample. The ellipses represent the 95% confidence interval for the groups. b Loadings plot for AKI stage. Loadings show how metabolites contribute to separation seen in the scores plot. PC principal component
