Role of intelligent/interactive qualitative and quantitative analysis-three-dimensional estimated model in donor-recipient size mismatch following deceased donor liver transplantation

Figure 1 Optimal cut-off values of the index in predicting massive intraoperative blood loss and early allograft dysfunction. A: The standard total liver volume index (sTLVi) value of 1.24 was the optimal cutoff value for predicting massive intraoperative blood loss, with a sensitivity of 46.3% and a specificity of 94.7%; B: The sTLVi value of 0.85 was the optimal cutoff value for predicting early allograft dysfunction (EAD) caused by small-for-size syndrome, with a sensitivity of 96.0% and a specificity of 88.0%; C: The sTLVi value of 1.32 was the optimal cutoff value for predicting EAD caused by large-for-size syndrome, with a sensitivity of 95.0% and a specificity of 85.0%. ROC: Receiver operating characteristic.

Figure 2 Overall survival of patients in 0. 85 < standard total liver volume index < 1.32 group was significantly superior to those in standard total liver volume index ≤ 0.85 group (P = 0.006) and sTLVi ≥ 1.32 group (P < 0.001). sTLVi: Standard total liver volume index.

Figure 3 The equivalence of the standard total liver volume index model and the estimation total liver volume index model in predicting massive intraoperative blood loss and early allograft dysfunction. A: The area under the curve (AUC) of standard total liver volume index (sTLVi) model and intelligent/interactive qualitative and quantitative analysis-three-dimensional (IQQA-3D) estimation total liver volume index (eTLVi) model in detection of massive IBL were 0.618 and 0.598 (Z = 0.889, P = 0.374), demonstrating equivalence; B: The AUC of sTLVi model and IQQA-3D eTLVi model in detection of early allograft dysfunction (EAD) caused by small-for-size syndrome were 0.932 and 0.889 (Z = 1.501, P = 0.133), demonstrating equivalence; C: The AUC of sTLVi model and IQQA-3D eTLVi model in detection of EAD caused by large-for-size syndrome were 0.933 and 0.922 (Z = 0.710, P = 0.478), demonstrating equivalence. eTLVi: estimation total liver volume index; sTLVi: Standard total liver volume index; ROC: Receiver operating characteristic.
