st: How to handle large (or small) odds ratios

[Tim Evans <Tim.Evans@wmciu.nhs.uk>]

Hi all,

Not specifically a Stata question, however, I have run a series of logistic regressions (in Stata) comparing the effects of delay in treatment  and a persons likelihood of dying within a given time period. I have exported the analysis in readiness to produce tables, but what I wanted to know is whether there is a convention for dealing with very large odds ratios when producing publication tables, in order to produce neat legible tables. Many of these large odds ratios are very significant. Any advice gratefully received.

Best wishes

Tim
