Fig. 3: Combined low expression of Bax, Bak and Smac is a combinatorial marker candidate for improved progression-free survival.

a Expression profiles based on the H scores of Bax, Bak and Smac (blue: automated H score below median, red: above median) in n = 50 patients. b Survival analysis for the cohort based on the expression profiles shown in a. Log-rank test for trend was used to compare three Kaplan–Meier curves representing patients with low Bax, Bak and Smac H scores (blue) vs. mixed and high expression (black and red, respectively).
