Hi all:
For stratified count data,how to perform regression analysis?
 
My data:
age case oc count
1       1     1    21
1       1     2    26
1       2     1    17
1       2     2    59
2       1     1    18
2       1     2    88
2       2     1     7
2       2     2   95
 
age:
1:<40y
2:>40y
 
case:
1:patient
2:health
 
oc:
1:use drug
2:not use drug
 
My purpose:
Anaysis whether case and oc are correlated, and age is a stratified variable.
 
My solution:
1,Mantel-Haenszel test by using function "mantelhaen.test"
2,loglinear regression by using function glm(count~case*oc,family=poisson).But I don't know how to handle variable "age",which is the stratified variable.
 
Many thanks for your help.

My best.
