  2. In each cell, the reference group consist of those who had no long-term LTSA due to each diagnostic group per occupational class. All models are adjusted for demographic variables
  3. 1 Disability retirement due to the same diagnostic group as in previous LTSA spell
  4. 2 Disability retirement due to some other diagnostic group than in previous LTSA spell
  5. 3 * p < 0.001 ** p < 0.02 *** p < 0.05. The significance level of the interaction test between occupational class and LTSA diagnostic group
