From: Survival models with preclustered gene groups as covariates
Kaplan-Meier curves for the high-risk and low-risk groups. Kaplan-Meier curves for the high-risk and low-risk groups defined by the estimated prognostic indices of the 67 patients in the test data set, the cutoff is defined as the median prognostic index on the test data. Genes, GO groups, and preclustered GO groups are used as covariates, respectively, and lasso regression is applied as model selection method.
