Establish and validate the nomogram of RadCLN-D. a For the radiological score and the clinical score, locate the corresponding value on the scale provided on the nomogram, then add up to get the total points. A vertical line from the total points value is to the predicted probability of the 1-year and 2-year survival probability. b Importance of the radiological score and the clinical score. c Calibration of the nomogram in terms of the agreement between predicted and observed 1-year survival outcomes
