Some concerns |
No information on allocation concealment, but baseline characteristics do not show any differences between the two groups |
Low risk of bias |
Single blinded study with the personnel aware of the intervention allocation, but there seems to be no deviations that arouse outside the trial context. Also all patients analysed as randomised. |
Low risk of bias |
Data reasonably complete for all the included patients |
Some concerns |
Since the outcome is a subjective one and that the assessors were aware of the intervention, there is a likelihood of assessment being influenced by the knowledge of the allocation group. |
Some concerns |
A trial protocol is not available for assessment |
High risk of bias |
Some concerns in more than one domain |

Low risk of bias |
Allocation concealed, sequence generation random and baseline characteristics does not reveal any imbalance between the two groups. |
Low risk of bias |
Though the personnel were aware of the intervention allocation, but there seems to be no deviations that arouse outside the trial context. Also all patients analysed as randomised. |
Low risk of bias |
Data reasonably complete for all the included patients at the time of discharge. Significant attrition at 3 and 6 months, though no outcomes assessed during this period was included in this analysis. |
Some concerns |
Since the outcome is a subjective one and that the assessors were aware of the intervention, there is a likelihood of assessment being influenced by the knowledge of the allocation group |
Low risk of bias |
Trial analysed as per a priori registered protocol. |
Some concerns |
Some concerns in one domain |
