Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | The trial was described as being randomised, but it was unclear how the sequence was generated. |
Allocation concealment (selection bias) | Unclear risk | The trial was described as being randomised, but it was unclear how the allocation was concealed. |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Only experimental group two received an enteral tube. |
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 serious adverse events properly (only total complications, not by group). |
For‐profit bias | High risk | The trial was funded by Bristol‐Myers Squibb. |
Other bias | Low risk | The trial appeared to be free of other components that could put it at risk of bias. |
