Pooled relative risks

2001-06-14 Thread JFC

Hi,

Relative risk is commonly used in Epidemiology and Medical Statistics.
It is simply the ratio of two proportions.

Because of some desirable properties, it is usual to calculate instead
of  it another index, the *odds ratio*, that is a good approximation  to

relative risk in many practical cases, but not in all.

I am concerned in the way of calculating  pooled relative risks, since
it is interesting in some *meta-analytical* applications. It is very
easy to find formulas to obtain pooled odds ratios (the most known is
Mantel-Haenszel's) but, up to now, I have not been able to find one for
pooled relative risks. Could you help me with that?

Thank you a lot.

See eg Rothman Modern Epidemiology P 196 et seq.
