Fig. 1. ROC analysis of the three scoring systems, LDH/ULN ratio, and modified PLASMIC-S for the prediction of patients with TMA due to severe ADAMTS13 deficiency assessed to be at high risk. (A) ROC curves (left) and comparative analysis (right) of the three scoring systems. (B) ROC curves (left) and comparative analysis (right) of the LDH/ULN ratio, PLASMIC-S, and modified PLASMIC-S.
Abbreviations: AUC, area under the curve; CI, confidence interval; LDH, lactate dehydrogenase; ULN, upper limit of normal (230 IU/L in our study); PLASMIC-S, PLASMIC score; TMA, thrombotic microangiopathy; ADAMTS13, a disintegrin and metalloprotease with thrombospondin type 1 motif, member 13.
