We randomly divided the patients into a training cohort and an internal validation cohort with an allocation of 7:3 ratio by R software v4.3.0. More information about the training and validation cohorts is shown in Table Patient characteristics of the training and validation cohorts.We used the x-tile v3.6.1 (Yale University) to determine the optimal cutoffs for tumor size and age.Univariate and multivariate logistic regression for analyzing associated factors for developing liver metastases.HR: hazard ratio; CI: confidence interval.
