Nomogram predicting 2 and 5-year recurrence-free survival in patients with resected primary GIST. Points are assigned based on tumor size, mitotic index, and site by drawing an upward vertical line to the “Points” bar. Based on the sum of the points generated, a downward vertical line is drawn from the “Total Points” line to calculate 2 and 5-year RFS.
