st: Confidence intervals for incidence rate

["Paul O'Brien" <paul.obrien@afe2.org.uk>]

I want to calculate the CI for a single incidence density:

5 pregnancies in 5240 months of exposure.

The delta method has been recommended. Can I use it in Stata?

There is the poisson:
 .cii #exposure #events, poisson [ level(#) ]

Epitab give CIs for the incidence rate ratio in � irr -, but not for the
individual incidence rates.

Thanks

Paul
