(A) ROC curve of Δ LPC (D1–D0, D3–D0, D7–D0) for predicting 28-day mortality (B) ROC curve of Δ LPC (D1–D0) compared to SOFA, APACHE II score. In ROC curve comparisons, the AUC of ΔLPC (D1–D0) was higher than SOFA (AUC 0.7 vs. 0.67, p = 0.712) or APACHE II score (AUC 0.7 vs. 0.692, p = 0.916) for predicting 28-day mortality, although there is no statistical difference.
