How to find OS duration, status information of patients in GSE1159 (Microarray data analysis)

Question

[sf.jeong510]

Hello, many papers showed survival analysis using GSE1159 (N Engl J Med 2004; 350:1617-1628 and etc...). Although I got pData in GSE1159 in R, I didn't find OS, status of patient infromation. how to get this information?

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.
