A: Forrest plot for the multivariate survival analysis including macrophages, Tregs, tumor stage (T-Stage), lymph node status (LN-Status) and adjuvant chemotherapy (Adj. Chemo). B: Overall survival probability for the ratio of macrophages to CD3 + T-cells p(Log-Rank) = 0.008. Patients with a ratio of ratio of < 50 macrophages to CD3+ T-cells were stratified as low and patients with a ratio of ≥ 50 as high. The cut-off was calculated using the cut-off finder with the minimum log-rank P-value method
