The outcome sick leave adjusted for age, sex, pain intensity, disability, depression, duration of sick leave (log) and the interaction joint physical job demands, employment and sex scores at baseline. The outcome disability adjusted for age, sex, depression (log), smoking, pain intensity, disability and the interaction joint duration of low back pain and physical job demands scores at baseline. The outcome pain adjusted for age, sex, disability, depression (log), duration of low back pain, smoking and the interaction joint sex and physical job demands scores at baseline
