Cochrane Scientific Committee recommendation (Full statement, July 2017):
ROBINS-I is the preferred tool to be used in Cochrane Reviews for non-randomized studies of interventions, although it is not mandatory, and will require author teams to have sufficient knowledge and experience to apply the tool. An alternative option is the Newcastle-Ottawa Scale. Please await further announcements on guidance and support to implement this tool.
