Dear all,

I have to produce a bar chart for % of patients who responded(ept = 1) at each time point for each treatment group. Percentages for each treatment/time point should be based on the total number of patients in each treatment group. at each time point with a non-missing response for ept. Ept has value of missing, 1 and 2.

There are 6 visits. Visit 1 2 3 4 5 6 Can someone tell me how do i find out the percentages of patients as per the above condition and plot a bar chart out of it.

Regards,
