  1. RMD = Roland-Morris disability questionnaire (a higher score indicates a more favourable outcome). VAS = visual analogue scale (a lower score indicates a more favourable outcome). Mean score of low back pain, leg pain and both. *Corrected for clustering effect. ¶ Mean difference between control and intervention groups over 26 weeks. † Odds ratio without baseline correction. ‡ Rate ratio in the multilevel model corrected for dichotomous baseline value. § Rate ratio without baseline correction
