How do I add p-values to boxplots?

[Magnus]

How do I add p-values comparing two of five groups using this code? I have attached an illustration of what I would like to show. Thanks 🙂

proc sgplot data=oligo25_log;
vbox logX / category=gruppe;
run;

"logX" is my marker of interest and "gruppe" is the group variable (in my case there are five groups).

Best regards, 
Magnus

I think you have to use PROC BOXPLOT with the ANNOTATE facility to create those types of p-values on your plots.

But why make your life difficult? Wouldn't a table of p-values (which is easily produced) suffice?

Thank you for a quick and useful reply! True, but it looks good to include the p-values as well..
