Given the dataset RAWB P that is sorted by SUBJECT TEST WEEK: ``` SUBJECT WEEK TEST VALUE 101 0 DBP 160 101 1 DBP 140 101 2 DBP 130 101 3 DBP 120 101 0 SBP 90 101 1 SBP 87 101 2 SBP 85 101 3 SBP 80 ``` The following SAS program is submitted: ```sas data bp; set rawbp; by subject test week; retain baseline; if first.test then baseline = .; if week > 0 then baseline = value; else if week > 0 then do; end; run; ``` Which statement must be added to the program to calculate relative change in percent (percent change) from baseline?

A. pct_chg = ((baseline - value) /baseline)*100;

B. pct_chg = ((value - baseline) /baseline)*100;

Question

This question will ask you to provide a line of missing code. Given the dataset RAWB P that is sorted by SUBJECT TEST WEEK:

SUBJECT WEEK TEST VALUE
101 0 DBP 160
101 1 DBP 140
101 2 DBP 130
101 3 DBP 120
101 0 SBP 90
101 1 SBP 87
101 2 SBP 85
101 3 SBP 80

The following SAS program is submitted:

data bp;
 set rawbp;
 by subject test week;
 retain baseline;
 if first.test then baseline = .;
 if week > 0 then baseline = value;
 else if week > 0 then do;
 <insert code here>
 end;
run;

Which statement must be added to the program to calculate relative change in percent (percent change) from baseline?

Options

Apct_chg = ((baseline - value) /baseline)*100;
Bpct_chg = ((value - baseline) /baseline)*100;
Cpct_chg = ((baseline - value) /value)*100;
Dpct_chg = ((value - baseline) /value)*100;
