Ding ZG and Xiao WJ contributed equally to this work as co-first authors. The follow-up and data collection of 133 patients included in this study were all completed by Ding ZG, which is a time-consuming and difficult task. Therefore, it is reasonable to list him as a co-first author. The data analysis and figure drawing involved in this article were mostly completed by Xiao WJ. She maintained the rigorous principle and ensured data authenticity in the process of data analysis, which justifies her as a qualified co-first author. Cai H and Zhang YC contributed equally to this work as co-corresponding authors. Cai H consulted a large amount of relevant literature and designed this study together with Gong Wei and Zhang YC. The details of the study (such as primary outcomes, secondary outcomes, influencing factors, etc.) were determined by Cai H, which makes it reasonable for him to become a co-corresponding author. Zhang YC also participated in the design of the study, and as an experienced surgeon, he was mainly responsible for calculating eTLV using IQQA-3D and carrying out further amendments if necessary. In addition, he was mainly committed to revising the manuscript, which makes it reasonable for him to become a co-corresponding author.

ARTICLE HIGHLIGHTS
Research background
Donor-recipient size mismatch (DRSM) is considered a crucial factor for poor outcomes in deceased donor liver transplantation (DDLT).
Research motivation
A feasible model for estimating the degree of DRSM is needed.
Research objectives
To identify benefits of intelligent/interactive qualitative and quantitative analysis-three-dimensional (IQQA-3D) liver volumetry in DDLT and establish an estimation model to guide perioperative management.
Research methods
A retrospective study was conducted to determine the accuracy of IQQA-3D liver volumetry and to establish an estimation total liver volume (TLV) index (eTLVi) model. Receiver operating characteristic curves and logistic regression analysis were used to detect the influencing factors for the occurrence of massive intraoperative blood loss (IBL) and early allograft dysfunction (EAD) in DDLT.
Research results
Recipient estimation TLV calculated using IQQA-3D highly matched with recipient standard TLV (P = 0.221). Alcoholic liver disease, gastrointestinal bleeding, and standard TLV index (sTLVi) > 1.24 were independent risk factors for massive IBL, and drug-induced liver failure was an independent protective factor for massive IBL. Male donor-female recipient combination, model for end-stage liver disease score, sTLVi ≤ 0.85, and sTLVi ≥ 1.32 were independent risk factors for EAD, and viral hepatitis was an independent protective factor for EAD. The overall survival of patients in the 0.85 < sTLVi < 1.32 group was better compared to the sTLVi ≤ 0.85 group and sTLVi ≥ 1.32 group (P < 0.001). There was no statistically significant difference in the area under the curve of the sTLVi model and IQQA-3D eTLVi model in the detection of massive IBL and EAD (all P > 0.05).
Research conclusions
IQQA-3D eTLVi model has high accuracy in predicting massive IBL and EAD in DDLT. We should follow the guidance of the IQQA-3D eTLVi model in perioperative management.
Research perspectives
By establishing the eTLVi model, the degree of DRSM was estimated and IQQA-3D proved to be of guiding value in perioperative management in DDLT.
