I don't remember this test exactly; however testing homogenity of the odds
ratio in K 2x2 tables is equivalent to testing interaction x:z in the
logistic model:
y~x+z+x:z
where y is the (binary) response variable, x is the (binary)
"exposure"
variable and z is the K-levels confounding factor,
best,
