Comments

1. Active components included in the intervention, in relation to the comparison

One component

The active component is the delivery of non‐invasive PAP therapy.

2. Behaviour or actions of intervention recipients or participants to which the intervention is directed

Single target

The intervention is directed at one behaviour, the nightly use of non‐invasive PAP therapy.

3. Organisational levels and categories targeted by the intervention

Single category

The intervention is directed at individual patients.

4. The degree of tailoring intended or flexibility permitted across sites or individuals in applying or implementing the intervention

Varies from inflexible to highly flexible

The intervention has potential to be tailored both in content (e.g. mask/interface) and form (e.g. pressure settings).

5. The level of skill required by those delivering the intervention in order to meet the intervention objectives

High level skills

Specialised clinical skills are required for prescription, setup and monitoring of the intervention.

6. The level of skill required for the targeted behaviour when entering the included studies by those receiving the intervention, in order to meet the intervention objectives

Intermediate level skills

Participants require education and training in order to apply the intervention at home.

7. The degree of interaction between intervention components, including the independence/interdependence of intervention components

Independent

The intervention has only one component.

8. The degree to which the effects of the intervention are dependent on the context or setting in which it is implemented

Varies from independent to highly dependent of context

This intervention is likely to be dependent on societal, economic and health system context.

9. The degree to which the effects of the intervention are changed by recipient or provider factors

Highly dependent on individual‐level factors

The intervention is likely to be dependent on the skills of the provider and the individual factors of the recipient.

10. The nature of the causal pathway between the intervention and the outcome it is intended to effect

Pathway variable, long

The causal pathway is complex and incompletely elucidated.
