Table 2 Potential subgroups for which outcomes are recorded

From: Barriers and facilitators to the implementation of orthodontic mini-implants in clinical practice: a protocol for a systematic review and meta-analysis

General subgroups

Specific subgroups

Stakeholders

Demand-side stakeholders: orthodontic patients and their family members

Supply-side stakeholders: clinicians, office staff, clinic owners, researchers, guideline developers, policy makers, implant companies, etc.

Users/non users: both demand- and supply-side stakeholders can be further subdivided in those that have used OMIs previously (users) and those that do not use these devices (non-users)

Interventions

Specified interventions: these interventions refer to a specific phase or type of the interventional procedure. Phases of the intervention refer to the: anesthetics, implant insertion, orthodontic treatment with OMIs, implant removal, or the healing phase. Types of interventions refer to the implant type and dimensions, number of implants, use of plates, the surgical procedure, implant location, timing and forces of orthodontic loading, etc. [41].

‘Non specified’ interventions: these interventions refer to ‘any orthodontic treatment with OMIs’. Additional information on the specific phase or type of the interventional procedure is not provided

Time points

Pre-intervention recordings, i.e., recordings of outcomes prior to the interventional procedure

Immediate post-intervention recordings, i.e., recordings of outcomes within 2 weeks after the completion of the interventional procedure

Long-term post-intervention recordings, i.e., recordings of outcomes more than 2 weeks after the completion of the interventional procedure.

Setting/Country

Private practice: stakeholders treated or working in a private practice

University setting: stakeholders treated or working in a university clinic

Country: stakeholders treated or working in a specific country

Research design

Surveys or questionnaires: outcomes obtained through either surveys or questionnaires

Interviews: outcomes obtained from interviews with stakeholders

Focus groups: outcomes obtained from focus groups with stakeholders
