Figure 3. Relationship between DRGs and prognosis. (A–J) Kaplan-Meier plots illustrated the relationship between DRGs and overall survival (OS). (K) COX forest plots illustrated the relationship between DRGs and patient prognosis. (L) Prognostic network plots for DRGs. The line connecting two DRGs represented their interaction, and the thicker the line, the stronger the association. Positive correlation was depicted by the pink line, while negative correlation was represented by the blue line.
