2.3. Randomization and concealment
EVENT, ACUTE HEPATIC FAILURE
With the aid of SPSS software (version: 14.0) (SPSS Institute, Anhui Medical University, Hefei, China), permuted-block randomization was carried out based on a computer system that used an allotment list to produce random numbers (in a 1-to-1 ratio). This was carried out by a statistician who was not a member of the research team to maintain the integrity and blinding of the research. The outcomes of the random sampling process were enclosed in prenumbered envelopes and kept at the location of the research until the study’s conclusion was reached. The study medicines were delivered by a research nurse following the random assignment sequence. Both the research participants and the patients were unaware of which medicine was being applied in the trial. In the event of an emergency, such as acute hepatic failure, 2 experts might recommend that the treatment allotment be unmasked and that the study medicine be adjusted or discontinued if needed, according to the protocol. All of the occurrences were recorded in detail. Then, we acquired information on the patient’s demographics, medical histories, and pertinent investigation findings.
