Fang 2009.

Methods	Quasi‐randomised controlled trial.
Participants	128 women randomised. Setting: First Affiliated Hospital of Xi’an Jiaotong University (Obstetrics Department) Inclusion criteria: women with singleton pregnancy presenting with antepartum itching and abnormal ALT and AST which resolved postpartum. Exclusion criteria: antenatal problems such as vomiting, loss of appetite, lethargy or any medical problems, known liver disease or hepatitis prior to pregnancy.
Interventions	Salvia+UDCA (N = 72). Salvia injection IV (10 mL in 10% 500 mL Dextrose) and UDCA 15 mg TDS PO for 14 days. UDCA (N = 56). UDCA 15 mg TDS PO for 14 days.
Outcomes	Maternal: reduction in pruritus score; monitoring of CG, TB, ALT and AST levels. Fetal/neonatal: CS for fetal distress; meconium‐stained liquor; Apgar score and birthweight.
Notes	Article in Chinese.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	High risk	Quasi‐randomised controlled trial. "A total of 128 patients were divided into two groups based on the date of admission into the First Affiliated Hospital of Xi'An Jiaotong University."
Allocation concealment (selection bias)	High risk	Quasi‐randomised controlled trial. "A total of 128 patients were divided into two groups based on the date of admission into the First Affiliated Hospital of Xi'An Jiaotong University."
Blinding (performance bias and detection bias) All outcomes	High risk	The route of administration of the interventions being compared were different and therefore blinding would not have been possible.
Incomplete outcome data (attrition bias) All outcomes	Low risk	There appear to be no losses to follow‐up.
Selective reporting (reporting bias)	Unclear risk	Results for outcomes described in the abstract and methods are reported. However, stillbirth, neonatal death or preterm birth are not reported.
Other bias	Unclear risk	It is unclear why there are 72 women in the experimental group and 58 women in the control group.
