Thresholds for unacceptable work state in radiographic axial spondyloarthritis of four presenteeism and two clinical outcome measurement instruments
Authors' conclusion
Thresholds of measurement instruments for presenteeism and health status to identify unacceptable work state have been established.

Performance
As reported in the abstract
Optimal thresholds for unacceptable work state
| Test or model | Threshold | AUC |
|---|---|---|
| WPAI-presenteeism | ≥40 | 0.85 |
| QQ-method | <97 | 0.76 |
| WALS | ≥0.75 | 0.87 |
| WLQ-25 | ≥ 29 | 0.85 |
| BASDAI | ≥4.7 | 0.82 |
| BASFI | ≥3.5 | 0.79 |
Threshold

Further findings
Prevalence of unacceptable work state and AWO · 12 months
- Unacceptable work state
- 15%
- At least one AWO in 12 months
- 6%
Stability across contextual factors
- WALS and WLQ-25 thresholds stable; others overestimated unacceptable work state in lower educated persons
Prediction of future AWO · 12 months
- Thresholds could predict future AWO, with lower performance, especially QQ-method, BASDAI and BASFI
