Kaplan-Meier survival curves. One hundred patients (N = 100) are divided into two groups with the macrophage densities above or below the median value. P values are obtained in comparisons of the two groups through a univariate analysis using the log-rank test. [M1] and [M2] represent the M1 macrophage density and M2 macrophage density, respectively.
