Murphy 2014.

Methods	Randomised controlled trial
Participants	Subfertile women aged 21 to 44, all under the care of Abington Reproductive Medicine and Genetics and requiring in vitro fertilisation–embryo transfer. Women were excluded if they were already enrolled in other in vitro fertilisation–embryo transfer clinical trials or undergoing pre‐implantation genetic diagnosis. 202 women were randomised into the intervention group (n = 101) and the control group (n = 101). Mean (SD) age was 33.6 (4.7) years in the intervention group and 34.1 (4.3) years in the control group
Interventions	The intervention group received harp music therapy during embryo transfer for 20 minutes, face to face, delivered by a certified music practitioner. The control group received usual treatment
Outcomes	Anxiety (measured by STAI) and clinical pregnancy rate
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Women were randomised per a random numbers table to the harp therapy group or the standard treatment group
Allocation concealment (selection bias)	Unclear risk	Not reported
Blinding of participants and personnel (performance bias) Subjective outcomes	High risk	Participants and personnel not blinded
Blinding of participants and personnel (performance bias) Objective outcomes	Low risk	Participants and personnel not blinded
Blinding of outcome assessment (detection bias) Subjective outcomes	Unclear risk	Not reported
Blinding of outcome assessment (detection bias) Objective outcomes	Unclear risk	Not reported
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	< 10% withdrawals and exclusions, women were excluded postintervention from the analysis, reasons given. No intention‐to‐treat analysis
Selective reporting (reporting bias)	Unclear risk	Unclear without access to the protocol
Other bias	Low risk	No other obvious sources of bias. A validated questionnaire was used for the primary outcomes
