Figure 2. High EDRN tumor EGFR protein by IHC was associated with reduced progression-free survival.

Figure 2

Kaplan-Meier progression-free survival plots by (A) tumor EGFR level by IHC Score tertile, (B) EGFR gene amplification status (presence versus absence), (C) EGFR protein level by RPPA by tertile and (D) EGFR mRNA level by tertile. Log rank tests with associated p values compare presence versus absence (B) or trend across low, intermediate and high tertiles (A, C & D).
