Hello Proc experts,

 

 

Please i need your input and help.

 

I have a dataset in which i want to use proc freq to get the percentage of patients who died for each value of my dichotomous heart complaint variable (0/1) and the odds ratio and 95% CI for heart complaint by died table.

 

I also want to merge (by tc tn) the odds ratio and 95%CI with the proportion who died to tell if there was any association between having the heart complaint and dying.

 

 

data me;
input Hear1	Heart2	Heart3	days	chddeath	death	tc	Tn $	value;
datalines;
0	1	1	629	0	1	1	Angina	0
0	1	1	629	0	1	2	Heartburn	1
0	1	1	629	0	1	3	Sleeplessness	0
1	0	1	1096	0	0	1	Angina	0
1	0	1	1096	0	0	2	Heartburn	0
1	0	1	1096	0	0	3	Sleeplessness	0
0	0	1	1096	0	0	1	Angina	0
0	0	1	1096	0	0	2	Heartburn	1
0	0	1	1096	0	0	3	Sleeplessness	0
1	0	1	1096	0	0	1	Angina	0
; run;
proc print; run;

/*sort dataset bt tc tn*/
proc sort data=two; by tc tn; run; 

/*to get an output that has oddsratio and outpct*/
Proc freq data =two noprint ; by tc tn  ; 
Tables value*death/out=twoa outpct cmh; 
proc print data = twoa; run;


/*to get an output that has only those that died*/
Proc freq data =two ; by tc tn ; 
tables death/out=twob ; run;
data twob; set twob; if death = 1; run; 

/*to merge both datasets*/
data three;
merge twoa twob;
by tc tn;
run;

 

My codes  are as written above and it did not give me the desired output that i was looking for. Please how can i get the OR and 95% CI using this format (Proc freq and options ).

 

Thanks
