*P-values below assumed a-level of 0.05 for statistical significance, ROM range of motion, SLR straight leg raise, PIT prone instability test, RMDQ Roland Morris Disability Questionnaire, NPRS Numeric Pain Rating Scale, PSEQ Pain Self-Efficacy Scale. ROM was considered ‘limited’ or ‘not limited’ by the assessor at first assessment compared to the time frame before LBP became obvious. Analyses were unadjusted for age and gender
