Outcomes
Participants were asked to indicate the solution that they preferred on a semantic differential scale, rated from definitely (5) to maybe (1) a preference for solution A or from maybe (1) to definitely (5) a preference for solution B. The DRPs were randomly reported as solution A or solution B to avoid bias related to the presentation of the scale. We derived a score from − 5 to + 5, where positive scores indicated the choice of DRP and negative scores indicated good practice or no DRP.
