Kaplan–Meier plots of PFS by combined CD${163}^{+}$ TAM marker based on high vs. low average number of communicating CD${163}^{+}$ cells and high vs. low median NND. (A) by four combinations of low/high average number of communicating CD${163}^{+}$ cells and low/high median cancer-to-CD${163}^{+}$ NND; (B) by combined CD163 marker with 3 categories: (1) low average number of communicating CD${163}^{+}$ cells and high median cancer-to-CD${163}^{+}$ NND; (2) low average number of communicating CD${163}^{+}$ cells and low median cancer-to-CD${163}^{+}$ NND; (3) high average number of communicating CD${163}^{+}$ cells and any median cancer-to-CD${163}^{+}$ NND.
