Interventions | Two study groups: 1. Music group: listening to self‐selected sedative music through earphones 2. Control group: standard care Music selections provided: (a) easy listening, (b) classical, (c) jazz Number of sessions: 2 sessions/day for POD 1 through 3 Length of session: 20 mins Categorized as music medicine |

Outcomes | Anxiety (STAI): 6 measurement points. Due to high number of missing values, only posttests POD1 am, POD1 pm and POD2 am were used in research report HR and SBP: 6 measurement points. Due to high number of missing values, only posttest POD1 am, POD1 pm and POD2 am were used in research report Pain (NRS): 6 measurement points. Due to high number of missing values, only posttests POD1 am, POD1 pm and POD2 am were used in research report | |
Notes | N is highly variable due to high number of missing data | |
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Flip of coin |
Allocation concealment (selection bias) | Low risk | Flip of coin prevented prior knowledge of randomization sequence |
Blinding of participants and personnel (performance bias) All outcomes | High risk | Blinding of participants was not possible. Personnel were not blinded. |
Blinding of outcome assessment (detection bias) Subjective outcomes | High risk | Self report measures were used for subjective outcomes |
Blinding of outcome assessment (detection bias) Objective outcomes | High risk | Outcome assessors were not blinded |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Not reported |
Selective reporting (reporting bias) | Unclear risk | Not sufficient information available to make judgment |
Other bias | Low risk | Supported by a grant from the Allina Foundation Nursing Research Trust Fund. |
