  1. The primary outcome (referral to secondary healthcare) was measured after 12 weeks and was collected from registries with a 100 % follow-up rate, representing 54 practices. The intra-class correlation for the primary outcome was 0.015 (95 % CIapproximate 0.011 to 0.069). The secondary outcomes (employment status, sick leave, satisfaction with received treatment, satisfaction with treatment results, Roland Morris Disability Questionnaire (RMDQ), back pain measured by numerical pain rating [back pain intensity], and EuroQol VAS (EQ VAS)) were measured after 4, 8, and 52 weeks. All secondary outcomes were collected from patient questionnaires. A total of 475 patients, representing 50 (83.3 %) practices, participated in the questionnaires
  2. aData are number (%) or differences (follow-up—baseline)
  3. bData are unadjusted odds ratios (OR 95 % CI), adjusted odds ratios (AOR 95 % CI), unadjusted mean differences (95 % CI), or adjusted mean differences (95 % CI). Adjustments are made for patients’ age, patients’ sex, and practice size
