Subject: st: trends (p-values) and annual percentage changes of directly standardized rates
Dear all,
I�m struggling with a problem since several days also I think it is only complicated for me;-( I tried to find a solution on my own via Internet for days now. However, unfortunately I was not successful and therefore I hope someone of this great community can help me with advice.
I need to calculate annual percentage changes (APCs) plus corresponding confidence intervals (CIs) and p-values for the trend of directly age-standardized rates (for female breast cancer).
I calculated the age-standardized rates and CIs using the distrate command.
I can also calculate APCs, CIs and p-values for the trend of APC using Poisson regression adjusting for age (using age-groups as categorical variable in the model). But this is not what I want. I can also calculate the APC and CIs for the directly standardized rates by using formulas of epidemiological textbooks. But then I have no p-value (which I need according to the task).
Can someone help me? I�m happy about any advice.
Thanks in advance
Anita
