Hello,
My dataset look like this:
VarA VarB
a 1.50 (1.25, 2.00)
b 0.70 (0.50, 0.90)
c 0.85 (0.70, 1.30)
VarB is a risk ratio estimate and 95% confidence interval. I would like to subset the observations where the confidence interval excludes 1.00 (VarA = a and b in this example). Could someone please suggest a program to parse VarB and subset accordingly? Thank you.
Untested:
data want;
set have;
*convert the lower/upper bounds to numbers;
lower=input(scan(varb, 1, "(),"), 8.2);
upper=input(scan(varb, 2, "(),"), 8.2);
*check if 1 is included;
if lower>1 or upper<1 then significant='Yes';
else significant='No';
run;
