Notes.

Data shown in the table: mean ± standard deviation; N (%); Wilcoxon rank sum test and chi-squared test for univariate analysis.

P < 0.05 was statistically significant and included in multivariate logistic regression (forward: wald).

Variables finally in the model (radiomics evaluation, NRS-2002, CT-reported LN status, and diabetes).
