After selection, 148 patients (112 in the training data set and 36 in the validation data set) who were enrolled in the MWA and chemotherapy group in the RCT were included to build and validate the prediction model. There were 85 events (progression or deaths) over a median follow-up time of 13.1 months (95% confidence interval (CI), 10.2 to 16.5 months). The median progression-free survival time was 10.3 months (95% CI, 8.0 to 13.0 months). The detailed characteristics of included patients in the training and external validation data sets are presented in Table
