Has anyone had experience calculating adjusted prevalence ratios (PR) and output the results including 95% CI?
Prevalence ratio is basically the ratio of two proportions. It is DIFFERENT from Odds Ratio, and it is commonly used in epidemiological studies. Different models/methods can be used for the calculation. My understanding is PR is similar to relative risk ratio, could the precedure used to calculate risk ratio used for PR?
I intend to create a model similar to the following. I would really appreciate if you can recommend methods and SAS codes for the calculation and output PR and 95%CI. (most factors are rare conditions)
model factor1 (event=1) = Race Adt1 Adt2
class Race
(Adt1, Adt2 are conditions to be adjusted, prevalence/proportion of factor1 are compared between Race: 2, 3 vs 1)
sample data: (or I can provide real data if you prefer)
ID Adt1 Adt2 factor1 factor2 factor3 factor4 Race
01 1 23 1 0 0 1 3
02 2 40 0 1 0 0 1
03 1 20 0 0 1 1 2
04 2 35 1 1 0 0 3
