For a 2 x k table [with a k-category "exposure" variable] just set up a logistic
dose-response model:

svyset <whatever>
svy: logistic <binary outcome var>  <exposure var>

and check the coefficient of <exposure var>, along with its confidence interval
and P-value.

If you prefer a risk metric rather than odds, then use svy: glm..... with
appropriate link and error specifications.
