The results of the simulation study verify that the sample size required to detect a 2×2 interaction in a mixed-effects linear regression model is fourfold that to detect a main effect of the same magnitude.
Dr. Trichopoulos said the study suggested "an effect of the same order of magnitude as taking an aspirin or exercising every day".
In our previous study,12 we saw no clear effect of the same dose of 20 ml olive oil on gastric emptying in healthy subjects.
The effect of the same parameters together with tooth thickness on the manufacturability of the individual gear teeth is also modelled in terms of pointing and undercutting.

In Experiment 2, the effect of the same enzyme as used previously (added at 0.51 μl/g forage DM, directly into the incubation medium), and buffer pH were examined using the ANKOM system, in a completely randomized design.
