Eg Paxil showed an effect size of 0.47, compared to Serzone’s 0.21. (After substracting the placebo effect's size of 1.2)
Suppose that antidepressants were a growth hormone pill taken by short people.
An effect size of 0.3 (standard deviation) is equivalent to a body height pill making you grow 0.8 in (2 cm), with placebo that's 2.6 in (6.6 cm).
