Scholarcy highlights

  • We conducted a scoping review using a list of network meta-analyses which incorporated nonrandomized evidence that were identified from a previous review
  • All NMAs that included NRE in the analysis of main outcomes or sensitivity analyses were eligible for inclusion
  • Most NMAs were supplemented with additional analyses to investigate the effect estimates when only randomized evidence was included
  • Most studies provided justification for the inclusion of NRE, transparent reporting of the method used to combine randomized evidence and NRE was unclear in most published networks
  • Availability of data and materials: All data are available from the tables, figures, and appendix of this study
