Plot time-vary drug exposure

zino — Sun, 14 Jun 2015 04:53:30 GMT

Because both the dose and duration of drug vary between subjects and within subjects over time

I use the time-depedent Cox regression to analyze it

However, how do I explain the consistence of drug use, that a user always a user or sometimes discontinue

I consider use of figure to explain how the dose and duration vary within individual, like the figure show as below

For example of my data and full data in the attached file. How do the sas plot the figure? Thanks you very much

ID	Prescribe data	Dispense duration	dose	date sequence
1	2000.1.1.	7	10	1
1	2000.1.15	27	15	14
1	2000.2.12	14	20	42
1	2000.2.27	28	15	57
1	2000.4.1	28	15	85

I am guessing on what you are asking. Here is one solution using SAS 9.4 SGPANEL Procedure using your data. I removed duplicates. Code is shown below.

data exposure;

set zino.exposure;

format prescribe_date date9.;

run;

proc sort data=Exposure out=Exposure2 nodupkey;

by id prescribe_date;

run;

ods graphics / reset width=5in height=6in imagename='Exposure';

title "Exposure by Subject Id and Date";

proc sgpanel data=exposure2;

label id='Subject id = ';

label prescribe_date='Prescribe Date';

label total_amt='Amount';

panelby id / layout=rowlattice rows=4 columns=1 onepanel noheader;

step x=prescribe_date y=total_amt / justify=right;

inset id / position=topleft textattrs=(size=10);

rowaxis offsetmax=0.2 grid;

colaxis grid;

run;

Thank you very much, It is what I want.

Is it possible to put all individuals figure in one figure? :smileyconfused:
