Figure 3.
X-Tile software was used to determine correlations between macrophage expression and survival time. The image color represents the correlation intensity of each partition from low (dark/black) to high (bright green/red). Green represents a direct correlation, and red represents a reverse correlation between expression level and characteristic survival rate. (A) The best cutoff value of CD68+ TAMs was 14.80%. The relationship between high and low CD68+ TAM expression and survival time is shown (P=0.002). (B) The best cutoff value of CD163+ TAMs was 18.30%. The relationship between high and low CD163+ TAM expression and survival time is shown (P=0.001). TAMs, tumor-associated macrophages.
