Hello. I want to analyze the survival of AML patients in GSE1159 and GSE6891. However, the datasets for these series do not have survival data (OS, status). Many papers have shown survival curves for these series. Please help me

my R code is below.

The code I used is below.

gset <- getGEO("GSE1159", GSEMatrix =TRUE, getGPL=FALSE)

if (length(gset) > 1) idx <- grep("GPL570", attr(gset, "names")) else idx <- 1

gset <- gset[[idx]]

info <- pData(gset)

clin.info <- rownames_to_column(info, var = "SN")

Thanks.
