Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Randomization was carried out by a third party using http:// www.randomization.com to generate the randomization sequence for the tomato juice interventions. |
Allocation concealment (selection bias) | Low risk | The sequence was given to the Dunedin hospital pharmacy, where a study dedicated pharmacist added the allocated amount of salt to the tomato juice. |
Blinding (performance bias and detection bias) All outcomes | Low risk | Single blind study |
Incomplete outcome data (attrition bias) All outcomes | Low risk | Lost to follow up 4/23 |
Selective reporting (reporting bias) | Unclear risk | No distinct selective reporting |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | The investigators remained blind to the randomization sequence throughout the study. Participants were initially blind to the randomization sequence, but once they began each phase of the intervention they were aware of the presence or absence of added salt. They were asked not to tell the investigator which tomato juice they had received. |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Outcome detection blinded |
