The statistical test indicates the mean of the macrophage distribution is less than the means of the CD8+ and FoxP3+ distributions, which is consistent with our observation that CD8+ and FoxP3+ cells show voids with large persistence in both the radius and codensity parameters in contrast to the CD68+ cells (see tumor TC in SI Appendix, Fig. S9 and Tables S4 and S7 ). This evidence concerns the gene CD68 and neoplasm.
