Blade, RELAX. I was NOT attempting to belittle you. I just did'nt know if you had read my post. Do you agree with me when I say that if the pooled 207 data resulted in a mean loss of 1.3 letters and the pooled 208 data resulted in a mean gain of 1.3 letters that there appears to be a synergy in the combination treatment? That's all I'd like to know.---biocrio
