B7-H6 and PD-L1 expressions features associations with TILs-PD-L1, TILs-B7-H6 and NK-TILs status. TILs-B7-H6 and TILs-PD-L1 were evaluated using the three-tier scoring system from high-power field (HPF) areas: 0–5%/HPF (Low), 5–50%/HPF (Medium), > 50%/HPF (High). Boxplot representations of H-score PD-L1 distribution according to TILs-PD-L1 status (a, p < 0.001), TILs-B7-H6 status (b, p < 0.001) and NK-TILs status (c, p < 0.001). Boxplot representations of H-score B7-H6 distribution according to TILs-PD-L1 status (d, p < 0.05), TILs-B7-H6 status (e, p = 0.768) and NK-TILs status (f, p < 0.05). Barplot representations showing NK-TILs distribution according to TILs-PD-L1 status (g, p < 0.01) and TILs-B7-H6 status (h, p < 0.001). Barplot representation of TILs-B7-H6 distribution among TILs-PD-L1 status (I, p < 0.001).
