Hi,

I'm performing a statistical analysis of diagnostic test data. I want
to calculate the 95% CI of the sensitivity and specificity for my
individual studies according to Diamond's formula, I have read that
this formula provides a very good aproximation to the exact method.

The question is that I don't know how to calculate the CI using
Diamond's formula. Any idea???

Thank you very much in advance,
