Wang 2010.
Methods | Two‐group parallel RCT, one centre ITT: yes Funding: supported by grant from Taipei Veterans General Hospital Overall study quality: high risk of bias No sample size calculation was reported |
|
Participants | 28 adult patients undergoing orthotopic liver transplantation. No exclusion criteria stated | |
Interventions |
Intervention group: monitored during surgery using point‐of‐care TEG analysis Control Group: monitored using standard laboratory measures of blood coagulation Specific trigger points for transfusion were established in each group with corresponding transfusion algorithms |
|
Outcomes | Outcome measures: 3 years mortality, transfusion requirements, total amount of IV fluids (fluid total, hydroxyethyl starch, albumin), blood loss, urine output | |
Notes |
Country: Taiwan. Language: English Letter sent to authors in November and December 2010. No reply received. Follow‐up: 3 years. No cross‐over Authors conclusion:"Thromboelastography‐guided transfusion decreases transfusion of fresh frozen plasma in patients undergoing orthotopic liver transplantation, but does not affect 3‐year survival" |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Unclear, no information provided. |
Allocation concealment (selection bias) | Unclear risk | Unclear, no information provided. |
Blinding (performance bias and detection bias) All outcomes | High risk | No data provided on blinding, but adequate blinding appears highly unlikely. |
Incomplete outcome data (attrition bias) All outcomes | Low risk | Appears to have adequate follow‐up. |
Selective reporting (reporting bias) | Low risk | Unable to compare with protocol or trial registration but appears to be free of selective reporting. |
Other bias | Low risk | Appears to be free of other types of bias. |
