Nomograms to predict 6-year DFS after second surgery in patients with recurrent RPS

Nomograms to predict 6-year DFS (A) and OS (B) after second surgery in patients with recurrent RPS. Instructions: Each nomogram provides a method of calculating the 6-year DFS or OS probability on the basis of a patient's combination of covariates. For instance, in the DFS nomogram, locate the patient-specific multifocality at second surgery, and draw a line straight up to the "Points" axis to determine the associated score. Repeat for the other nomogram variables, sum the scores, and locate the total score on the "Total points" axis. Draw a line straight down to the "6-year DFS probability" axis to obtain the probability.
