HR, Hazard ratio; s.d., standard deviation; CI, confidence interval.

Sample sizes for some variables were smaller due to missing data. For general health perceptions and physical functioning, n = 666; for pain, n = 664; for work impairment, n = 464 (due to the fact that many participants were not working outside the home).

For ease of interpretation of hazard ratios, we reversed the raw score and then divided it by 10, such that 0 represents good health and 10 represents poor health.

p < 0.01.
