[1] Was the assignment to treatment groups truly random? [2] Were participants blinded to treatment allocation? [3] Was allocation to treatment groups concealed from the allocator? [4] Were the outcomes of people who withdrew described and included in the analysis? [5] Were those assessing outcomes blind to the treatment allocation? [6] Were the control group and treatment groups comparable at entry? [7] Were groups treated identically other than for the named interventions? [8] Were outcomes measured in the same way for all groups? [9] Were outcomes measured in a reliable way? [10] Was appropriate statistical analysis used? Cited from Ha Dinh TT et al.
