Table 5 Quality assessment of the included RCT studies

From: Community-based interventions to increase dairy intake in healthy populations: a systematic review

Author* Was true randomization used for the assignment of participants to treatment groups? Was allocation to treatment groups concealed? Were treatment groups similar at the baseline? Were participants blind to treatment assignment? Were those delivering treatment blind to treatment assignments? Were outcomes assessors blind to treatment assignment? Were treatment groups treated identically other than the intervention of interest? Was follow-up complete and if not, were differences between groups in terms of their follow-up adequately analyzed? Were participants analyzed in the groups to which they were randomized? Were outcomes measured in the same way for treatment groups? Were outcomes measured in a reliable way? Was appropriate statistical analysis used? Was the trial design appropriate?
