WILCOXON TEST. COMMAND : signrank

Hi Angela,

The outcome parameter is total morphine consumption.

There was an error with the command you suggested as- signrank morphine, by (group)

However, with the command- ranksum morphine,by(group)- you get the p value.

But I want also the median difference(CI) in morphine comsumption between two groups.

Thanks in advance.

You want to use -qreg-, which is quantile regression. The default quantile is the median (i.e., median regression)
