How to compute the percentage changes of continuous variables?

I have a phenotype data (contineous) from a group of patinets who treated a with a drug A. I would like to see what is the percentage inceremnet or decreamnet in the values of phenotype in those patinets. How can I do this?

I would like to plot the percentage changes in these variables!

Post sample data and expected output. A sample of the graph your after is helpful, that article is behind a paywall.

A data step and proc SGPLOT are possibly all you require.

Give you an example:





data have;
input cat $ group $ res low high star;
cards;
F 1 12 10 14 16
F 2 14 12 15 .
M 1 20 18 22 23
M 2 18 17 20 .
;
run;
proc sgplot data=have;
vbarparm category=cat response=res
 /group=group groupdisplay=cluster limitlower=low limitupper=high;
scatter x=cat y=star/discreteoffset=-0.22 markerattrs=(symbol=starfilled);
run;
