Rau 1995	Started as a randomised clinical trial but did not continue because of problems with nozzles of jet cutter. So, the report consisted of non‐randomised patients.
Richter 2009	In this randomised clinical trial, if the patients did not undergo liver resection, the envelopes were resealed and returned to the pool of sealed envelopes. The allocation concealment is not adequate in this trial.

Schilling 2009	Comment on Richter 2009
Schwartz 2004	In the control group a number of topical haemostatic agents were used.
Shu 2014	In this study, patients were divided into 4 groups ‐ people who received blood transfusion and ulinastatin, people who received blood transfusion but not ulinastatin, people who received ulinastatin but not blood transfusion, and people who did not receive blood transfusion or ulinastatin. Although the authors randomised patients to ulinastatin or control, they ensured that the number of patients in each group was the same, i.e. the number of people in ulinastatin group who received blood transfusion was 50% and the number of people in control group who received blood transfusion was 50%. This would have seriously impaired the randomisation to the extent that we feel that this is not a randomised clinical at all.
