| Adequate method of randomization | 57 | 43.5% |
| Adequate method of allocation concealment | 41 | 31.3% |
| Similarity at baseline regarding the most important prognostic indicators | 89 | 67.9% |
| Appropriate patient blinding to the intervention | 30 | 22.9% |
| Appropriate care provider blinding to the intervention | 4 | 3.1% |
| Appropriate outcome assessor blinding to the intervention | 66 | 50.4% |
| Similar or no cointerventions between-groups | 40 | 30.5% |
| Acceptable compliance in all groups | 53 | 40.5% |
| Described and acceptable drop-out rates | 99 | 75.6% |
| Similarity of timing of the outcome assessment in all groups | 118 | 90.1% |
| Inclusion of an intention-to-treat analysis | 57 | 45.5% |
| Absence of selective outcome reporting | 78 | 59.5% |
