odds ratio for 10 unit increase in age

femiajumobi1 — Thu, 02 Feb 2023 16:41:39 GMT

Proc logistic data = B30, 
Model medication (ref="0") = age;
units age=10;
run;

I am trying to obtain 95%CI for 10 unit increase in age. the results show for odds ratio for age but not the 95%CI. It is not clear if am doing it wrong. adding "estimate and exp cl" to the line of code estimate units age=10/exp cl shows syntax error.

Hi @femiajumobi1,

To obtain the confidence interval, you can either use the CLODDS= option of the MODEL statement, e.g.,

model medication (ref="0") = age / clodds=wald;

or add an ODDSRATIO statement after the UNITS statement:

oddsratio age / cl=wald;
