Table 2 ICC results, upper bound (Ubound), and lower bound (Lbound) with a 95% confidence interval belonging to the 24 robust features in the current study. Radiomic features were categorized based on their ICC into four groups, comprising 1) 90%≤ICC<100%, 2) 75%≤ICC<90%, 3) 50%≤ICC<75%, and 4) ICC<50%. Radiomic features with more than 75% ICC were selected as robust features and shown in this Table.
