n = 1127 transition intervals.

Symptom improvement: move from higher to lower symptom state

Sustained reduction: remain in lower symptom state

TAU: Treatment as usual

RMDQ: Roland-Morris Disability Questionnaire; higher state ≥14

PHQ-9: Patient Health Questionnaire for depression; higher state ≥11

CPG: Chronic Pain Grade; higher state ≥50
