Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients will be randomised to receive either:
- Terlipressin at 0.85mg IV push, OR
- Placebo (Normal Saline 0.9%)

The study treatments will be macroscopically identical and will be supplied in identical 5 ml syringes prepared by ICU research staff.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be by means of sealed envelopes with permuted blocks of variable size.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Statistical methods / analysis
Outcomes will be compared after log transformation where appropriate. Comparisons will be made using t-test and ANOVA for repeated-measures or Wilcoxon rank-signed test and Kruskall-Wallis according to the underlying distribution for continuous data and Chi-square for categorical data. A Kaplan-Meier curve with log-rank test will be performed to further compare in-hospital mortality and rate of discharge home. Logistic regression analysis will also be performed to adjust for baseline imbalances. Analysis will be on intention-to-treat.
