To the Editor: We appreciate Dr Teboul’s careful reading of the publication that arose from our roundtable conference. His comments about the magnitude of a difference between active treatments using the NICE guidelines are reasonable up until he critiques the meta-analysis of mirtazapine and SSRIs.1 Here, he focuses on the slight remission rate difference in favor of mirtazapine (NNT = 23) and claims that we were misleading readers by failing to interpret "minor differences as anything more than clinically negligible." He then goes on to question if the coauthors of the paper who were employees of the pharmaceutical company spun the data in favor of mirtazapine.
Dr Teboul fails to mention, however, that we reported that the meta-analysis showed that the mirtazapine group had a 74% greater chance of remission during the first 2 weeks of treatment, that we included a careful and extensive discussion in the mirtazapine paper about the limitations of the data and the meta-analysis, that we had a specific discussion of factors that might bias the findings, and that we had an explicit modest statement in the paper that the results "provide some further support for the notion that antidepressants that enhance serotonergic and noradrenergic neurotransmission convey efficacy advantages relative to SSRIs [italics added]."1
Dr Teboul may want to consider reading source materials more carefully before he feels compelled to keep others honest.
