PRECIS-2 domain ratings and rationale for the BeatPain study⁷⁷

Domain score rationale
1. Eligibility criteria	4	Broad definition of chronic low back pain with minimal exclusion criteria.
2. Recruitment	4	Electronic referrals to outside providers are part of routine procedures in primary care. The population health recruitment strategy leverages tools available in routine practice, but are used less commonly.
3. Setting	5	Participating primary care clinics are usual care settings. Telehealth care is now part of routine care.
4. Organisation	3	Additional training is provided to physical therapists providing treatments. A minimal amount of training is provided to primary care clinic staff and providers.
5. Flexibility: intervention delivery	3	Intervention components use specific protocols that predetermine the number of sessions while providing flexibility for delivering content within sessions. Self-report measures of provider fidelity are used.
6. Flexibility: participant adherence	5	Participants are reminded about upcoming sessions and contacted if sessions are missed as is done in usual care. Participants are not pre-screened for likelihood of adhering or withdrawn for low adherence.
7. Follow-up	2	The amount and frequency of data collection from participants is more than usual care.
8. Primary outcome	4	The PEG outcome is highly patient-centred and is commonly available through EHRs for use in usual care, although routine use is not common.
9. Primary analysis	5	Primary analyses use intention-to-treat principles. Participants are included regardless of compliance.

Domains are scored from 1 (fully explanatory) to 5 (fully pragmatic).
