comparison between prevalences

#1
Hello, I would like to make a comparison between the prevalences of a disease by applying two guidelines to the same sample. I stratified the sample by age group and I calculated the disease prevalence rate according to the two guidelines for each subgroup divided by age. Now, I don't really know how to proceed. which test should I use? Can you help me? Thank you

Each subject has 3 information, age group, disease according to guideline 1 yes/no, disease according to guideline 2 yes/no.
For the total group and/or within each age group, you can compare the guideline variables using McNemar's test.

With kind regards
