Hi
I have two different models in stata
One covers the period 1970-1999 and gives an odds ratio of 1.35 with a confidence interval of (1.10,1.64)
And the second is a subset of the data covering a shorter time period and gives odds ratios of 1.56 with confidence interval(1.17,2.07)
My question is , is there a way in stata to formally test if the change in the odds ratio is significant,
Thanks
Ann
