Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | High risk | Comment: The method of randomisation was not reported. Uneven groups were generated. |
Allocation concealment (selection bias) | Low risk | Quote: "Twenty‐eight capsules of each were put into a non‐transparent enclosed sachet by randomised method." Comment: Each trial arm had the same number of tablets in concealed opaque sachets. Although the report did not state that these sachets were sequentially numbered, we have taken the view that allocation concealment was achieved. |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | Quote: "...double blind." Comment: All participants received the same tablet regimen and number of tablets. Whilst it was not specifically stated if the participants were blinded, it was felt they were likely to be unaware of which study group they had been allocated; therefore, we judged this domain to be at low risk. |
Blinding (performance bias and detection bias) All outcomes | Unclear risk | Comment: There was no report regarding where the tablets were accessed from/their distribution/how instructions were given. |
Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | Comment: It was not clear from the report whether the outcome assessor was blinded; therefore, we judged this to be at unclear risk. |
Incomplete outcome data (attrition bias) All outcomes | Low risk | Quote: "The study initially included 140 participants, 133 of them completed all the phases of they study and met all the criteria." Comment: The authors did not specifically describe why 7 participants were not included in analysis. The attrition rate was 5%. |
Selective reporting (reporting bias) | Low risk | Comment: The study protocol was not available. However, the outcomes stated in the methods of the report were all described in the results and discussion. |
Other bias | Low risk | Comment: This appeared to be free from other potential sources of bias. |
