Potential differences between Naughton et al 201613 and the repeat study
| Naughton et al 201613 (stage one) | Repeat study | Considerations |
| No previous exposure to medicine authentication (MA) technology | Previous exposure to MA technology | Previous results have not identified an association between technology exposure and increased compliance. There was a greater than 1-year interval between the studies |
| Conducted as a service evaluation study | Conducted as a research study | The repeat study involved ethical approval and written consent |
| This study was proposed by the principal investigator | This study was based on a consensus improvement (audio alarm) suggested by the participants | Compliance may have been affected by the motivation to implement an idea that was suggested by the participants |
