	Described as a RCT?	Was the method of randomization adequate?	Was the treatment allocation concealed?	Were the investigators blinded?	Were groups similar at baseline on important characteristics that could affect outcomes?	Was overall drop-out rate ≤20%	Was the differential drop-out rate at endpoint ≤15%?	High adherence to intervention protocols?	Were other interventions avoided or similar in the groups?	Outcome measures clear, reliable and valid? Implemented consistently?	Sample size sufficient to detect difference with at least 80% power?	Were outcomes reported or subgroups analyzed pre-specified?	Were all randomized participants analyzed in the group they were originally assigned?
