I need advice about how to calculate a significance test (trend test) for comparing the incidence rates over the years. I need to comment on whether there is a significant increase or decreas (with p-value for a trend) for incidence rates over the years.
Please see the attached data. My denominator for incidence is 100,000 for all.
I would really appreciate if anyone can help me with the SAS code.
