Compare groups

What to do: Define two patient subgroups and ask K Pro to compare them across a specific data type. Always specify the statistical test you want (log-rank, Cox, t-test) for precise results.

Example prompt:

In the TCGA-STAD cohort, test whether there is a statistically significant difference in overall survival between microsatellite-instable (MSI-H) and microsatellite-stable (MSS) patients. Report the hazard ratio, 95% confidence interval, and log-rank p-value.

Expected result: Statistical test results with HR, CI, and p-value, plus a supporting KM curve.

Follow-up:

Run a multivariate Cox regression adjusting for age, stage, and MSI status to confirm whether MSI status is an independent prognostic factor.
