WebReply and comments suggested two ways: Use Fisher's well-known formula using "z-tranformation" of r; Use comparison of slopes (regression coefficients). The latter could be easily performed just via a saturated linear model: Y = a + b X + c G + d X G, where X and Y are the correlated variables and G is a dummy (0 vs 1) variable indicating the ...
