Kaplan-Meier survival analysis with log-rank test of CD163+ TAMs.

<p>(a) Survival curves of the low density (score 0) (n = 38) vs. high density (score 1 and 2) (n = 92) groups in IF (SIF + EIF). (b) Survival curves of the low density (score 0) (n = 51) vs. high density (score 1 and 2) (n = 85) groups in TC (STC + ETC). (c) Survival curves of the low density (score 0) (n = 41) vs. high density (score 1 and 2) (n = 92) groups in S (SIF+STC). (d) Survival curves of the low density (score 0) (n = 52) vs. high density (score 1 and 2) (n = 78) groups in E (EIF+ETC). (e) Survival curves of the five subgroups determined by the total score in four combined areas (SIF + STC + EIF + ETC) (I, score 0 (n = 25); II, score 1 (n = 25); III, score 2 (n = 26); IV, score 3 (n = 25) and V, score 4 (n = 27)). (f) Survival curves of the low density (score 0) (n = 25) vs. high density (score 1–4) (n = 103) groups in four combined areas (SIF + STC + EIF + ETC). <i>Abbreviations</i>: TC, tumor center; IF, invasive front; S, stroma; E, epithelium.
