Figure 4.

Kaplan-Meier survival plots for the 295 NKI tumors/patients using the in vivo defined EGFR-associated profiles. The average expression value for each cluster in each patient was determined and the patients then put into rank-order and divided into two equal groups or three equal groups. Overall survival analysis was performed for each cluster. X indicates censored data due loss to follow-up or to information at last checkup. Note that Clusters #2 and #3 were also similarly prognostic for the UNC 248 training data set.
