Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Random‐numbers table |
Allocation concealment (selection bias) | Unclear risk | Not described |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | Coded black infusion bags |
Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | Not described |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | The number of participants with incomplete data was not reported. |
Selective reporting (reporting bias) | Unclear risk | No protocol could be obtained and the trial did not report mortality or serious adverse events. |
For‐profit bias | Low risk | "This study was supported by the Spanish Ministry of Health Grant FIS 97/ 0932.". |
