Hi,
You just need to construct a standard survival regression model of the form (in R):
library(survival)
Surv(Months, DFS) ~ gene1 + gene2 + gene3
NB - 'DFS' = disease-free survival
I have a tutorial here: Survival analysis with gene expression
###
For a quick example, try something like:
library(survminer)
ggsurvplot(survfit(Surv(Months, DFS) ~ gene1 + gene2 + gene3, data = survplotdata),
data = survplotdata,
risk.table = TRUE,
pval = TRUE,
break.time.by = 500,
ggtheme = theme_minimal(),
risk.table.y.text.col = TRUE,
risk.table.y.text = FALSE)
