- WAI scale 7–49 points (higher values indicate greater work ability); LiSat-11 scale 1–6 points (higher values indicate greater well-being)
- Using the cut-off points means that the values strictly below the cut-off point are classified as NRTW
- RTW return to work, AUC Area under curve, CI Confidence Interval, n number of observations, Max the maximum value of the sensitivity and specificity
