Stratify your samples by any data (e.g. expression, copy number, subtype, age, etc) and determine if there is a statistically significant survival difference.
Start with our walk through, or by going to our Visualization tab and using the wizard to get the data you would like to use to stratify your samples into the Visual Spreadsheet. Once your data is on the screen, click the caret menu at the top of the column and choose 'Kaplan Meier Plot'.
If your plot has an '!' icon next to the p-value this means that some samples are in your plot twice (e.g. normal and tumor). Learn how to remove duplicate samples.
