title: Prognostic factors for work ability in women with chronic low back pain consulting primary health care: a 2-year prospective longitudinal cohort study.
abstract: OBJECTIVE
  To investigate prognostic factors for future work ability in women with chronic low back pain (CLBP) consulting primary health care.
  
  
  METHODS
  A 2-year prospective longitudinal cohort study of female patients with CLBP within the primary health care was conducted. Patients were assessed at the first assessment and after 2 years. Prognostic factors for work ability (yes/no) were analyzed by multivariate regression.
  
  
  RESULTS
  A total of 130 patients were included at first assessment. After 2 years, 123 patients (95%) were followed up. The 6-minute walk test, depression, and earlier work ability predicted work ability at the 2-year follow-up. A nomogram was constructed to assess the probability of future work ability.
  
  
  CONCLUSIONS
  The 6-minute walk test, work ability, and depression predicted work ability for women with CLBP after 2 years.
