From: A pseudo-R2measure for selecting genomic markers with crossing hazards functions
Kaplan-Meier curve of the groups according to the expression levels of genes (a) FGFR2 , (b) MCL1 , and of the groups defined by the four combinations of expression levels of (c) FGFR2 and FGF4 , and (d) MCL1 and BCL2 in the lung cancer study. The groups of patients were determined according to the low-high expression status of the genes considered. Patients whose expression measurement was higher (resp. lower) than the median were assigned to the "highly expressed" (resp. "lowly expressed") group.
