Abbreviations: 1: The election criteria were specified; 2: The subjects were randomly assigned to the groups (in a cross-over study, the subjects were randomly distributed as they received the treatments); 3: The assignment was hidden; 4: The groups were similar at the beginning in relation to the most important prognostic indicator; 5: All subjects were blinded; 6: All therapists who administered the therapy were blinded; 7: All evaluators who measured at least one key result were blinded; 8: The measurements of at least one of the key results were obtained from more than 85% of the subjects initially assigned to the groups; 9: Results were presented for all subjects who received treatment or were assigned to the control group, or when this could not be done, the data for at least one key result were analyzed by “intention to treat”; 10: The results of statistical comparisons between groups were informed for at least one key result; 11: The study provides punctual and variability measures for at least one key outcome; Score: Each criterion met (except the first); N: Did not meet criteria; Y: Met criteria.
