We read with interest the recent paper on network meta-analysis (1) in which efficacy and tolerability of selected antiepileptic drugs in people with refractory focal epilepsy were compared. Whilst network meta-analysis may be a powerful tool, the validity of the results must depend on the selection of studies included. In this respect, we are curious about several methodological points. The authors include some studies, but not others that are of the same nature; the authors deem as appropriate doses that most experienced epilepsy clinicians would consider unusual; and the results that emerge would be considered misleading by most experienced epilepsy clinicians.
