Construction of the nomogram model. A nomogram model to evaluate the risk of MVI occurrence in HCC (A). To use the nomogram, determine the position of each variable on the corresponding axis, draw a line to the points axis for the number of points, add the points from all the variables, and draw a line from the total points axis to determine the MVI probabilities at the lower line of the nomogram. ROC and AUC curves in the training cohort (B) and the validation cohort (C). Abbreviations: glypican 3 (GPC3); ribonucleotide reductase catalytic subunit M1 (RRM1); breast cancer gene 1 (BRCA1); arginase (ARG)
