Clarifying a statement about efficacy of FGA, SGA

We appreciate Dr. Nasrallah referencing our work to assert that “most SGAs are similar to FGAs.” (Current Psychiatry, Comments & Controversies, October 2013, p. 39-40; http://bit.ly/177QOy6). What we actually found in our 20031 and 20112 meta-analyses was that “some antipsychotics are more efficacious than others,” and the first-generation antipsychotic vs second-generation antipsychotic distinction is not very useful clinically.3 These findings have repeatedly been replicated.3
