From: A 19-Gene expression signature as a predictor of survival in colorectal cancer
Survival analysis. Kaplan–Meier survival analysis using six different microarray datasets (Training and test sets (Illumina-based), dataset from Denmark (Affymetrix), dataset from the USA (Affymetrix) and dataset from Australia (Affymetrix)). The 19-gene signature segregates patients into two risk groups (red, high risk; black, low risk). The p values correspond to the likelihood ratio test comparing the survival curves
