title: NICE v. SIGN on psychosis and schizophrenia: same roots, similar guidelines, different interpretations.
abstract: A recent editorial claimed that the 2014 National Institute for Health and Care Excellence (NICE) guideline on psychosis and schizophrenia, unlike its equivalent 2013 Scottish Intercollegiate Guidelines Network (SIGN) guideline, is biased towards psychosocial treatments and against drug treatments. In this paper we underline that the NICE and SIGN guidelines recommend similar interventions, but that the NICE guideline has more rigorous methodology. Our analysis suggests that the authors of the editorial appear to have succumbed to bias themselves.
