  1. aEligibility criteria were specified; bParticipants were randomly allocated to groups, cAllocation to groups was concealed, dThe groups were similar at baseline regarding the most important prognostic indicators, eParticipants were not aware of the group, in which they were allocated (blinded), fStaff that administered training was not aware (blind) of the group status (intervention-control), gAssessors measuring at least one key outcome were not aware (blind) of the group status, hMeasures of at least one key outcome were obtained from more than 85 % of the subjects initially allocated to groups, iAll subjects for whom outcome measures were available received the treatment or control condition as allocated or, where this was not the case, data for at least one key outcome were analysed by “intention to treat”, jThe results of between-group statistical comparisons are reported for at least one key outcome, kThe study provides both point measures and measures of variability for at least one key outcome
