The ROC analysis of PLT, PDW, PPR, PDW + ABSI score, PPR + ABSI score and ABSI scores predicting the 120-day mortality of severe burn patients. ROC–AUC of ABSI score was 0.818 (95% CI: 0.774–0.862). (A) The AUC values of PLT, PDW, PPR, PDW + ABSI score and PPR + ABSI score on day 1 were 0.655 (95% CI: 0.591–0.719), 0.646 (95% CI: 0.583–0.709), 0.672 (95% CI: 0.608–0.737), 0.832 (95% CI: 0.789–0.874), and 0.834 (95% CI: 0.793–0.875), respectively. (B) The AUC values of PLT, PDW, PPR, PDW + ABSI score and PPR + ABSI score on day 3 were 0.792 (95% CI: 0.742–0.842), 0.782 (95% CI: 0.734–0.830), 0.816 (95% CI: 0.767–0.864), 0.861 (95% CI: 0.823–0.898), and 0.868 (95% CI: 0.832–0.905), respectively. (C) The AUC values of PLT, PDW, PPR, PDW + ABSI score and PPR + ABSI score on day 7 were 0.724 (95% CI: 0.666–0.783), 0.764 (95% CI: 0.713–0.815), 0.750 (95% CI: 0.692–0.807), 0.858 (95% CI: 0.817–0.899), and 0.850 (95% CI: 0.809–0.891), respectively. ABSI, abbreviated burn severity index; AUC, area under the curve; CI, confidence interval; PDW, platelet distribution width; PLT, platelet count; PPR, PDW-to-PLT ratio; ROC, receiver operating characteristic curve.
