Can anyone help me clarify the doubt regarding the coding pattern. I am trying to run a Poisson regression with Incidence rate Ratio for diarrhea for a CASE and CONTROL study.

Earlier I put code 1 for the CASE and 2 for CONTROL. Later I changed the code as 1 for CASE and 0 for CONTROL. Due to this I saw the change in the results. Can anyone suggest me what is the correct way of assigning codes to the dependent and independent variable.

any reference for interpretation of the results will be mush helpful. Please Cc the response to my email ID also as I am not sure if my email ID is still included under the forum.

Thanks
Priyajit
