Results from separate prospective binary logistic regressions estimating effects of shift work at baseline on reporting mild-to-severe chronic pain of single pain sites at follow‐up 7 years later
| Outcome | OR/IRR | 95% CI |
|---|---|---|
| Neck pain | 0.99 | (0.75, 1.29) |
| Arm pain | 0.96 | (0.71, 1.28) |
| Upper back pain | 0.99 | (0.69, 1.41) |
| Low back pain | 1.03 | (0.77, 1.37) |
| Hip or leg pain | 0.93 | (0.70, 1.23) |
| Other pain | 1.07 | (0.63, 1.72) |
| Any chronic pain | 1.41 | (0.97, 2.01) |
| Chronic widespread pain | 1.06 | (0.59, 1.80) |
| Number of chronic pain sites | 1.16 | (0.88, 1.52) |
Binary logistic regressions were run for separate pain outcomes, binary logistic regressions were run for ‘any chronic pain’ and ‘chronic widespread pain’, and Poisson regressions were run for ‘number of chronic pain sites’
