Now, in statistics, you're familiar with an effect size, which is basically how meaningful is an effect, because you can have a significant effect that isn't very meaningful if you have enough subject number. So when we say things like an effect size, 0.2 is considered small, 0.5 is considered moderate, and 0.8 is considered large, anything above 0.8. SSRIs are typically in the 0.3 to 0.5 range.
