Figure 3. PD-L1 expression on TILs or tumor cells and its correlation to OS and PFS in TNBC patients.

Figure 3

Kaplan–Meier overall survival (OS; (A) p = 0.87) and progression free survival (PFS; (B) p = 0.62) curves in patients with different PD-L1 expression on tumor cells are displayed. There were also no correlation detectable between overall survival (OS; (C) p = 0.31) and progression free survival (PFS; (D) p = 0.14) in patients with different PD-L1 expression on TIL. The p values were calculated using the log-rank test (Mantel-Cox).
