To the Editor We read the network meta-analysis on pharmacological, psychotherapeutic, and combination treatments for posttraumatic stress disorder (PTSD) published by Merz et al1 with great interest. In this meta-analysis, the authors found that psychotherapy alone and the combination of pharmacological and psychotherapeutic treatments were significantly associated with better outcomes than pharmacotherapy alone at long-term follow-up assessment, while all approaches demonstrated similar results at the end of short-term treatment. We have some concerns about this network meta-analysis.
