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,
vito
