That could be said for all the results presented. To be convincing, you really need to present the sample size (which, to be fair, you did do for some of the supplements in the discussion) and compute a simple statistical test -- I think Student's T-test would be appropriate here. If you don't have a stats book handy, write to me privately and I'll provide the necessary formulas (it's really rather simple). This will let you put a boundary on the probability that any result is simply due to chance. Regards, -- Joe ,------------------------------------------------------------------. | Joseph J.
