Overall effect of clinical judgement on HIA1 assessment accuracy
| Overall accuracy | Overall % (90% CI) |
| Theoretical accuracy (strict interpretation of subtests according to baseline value) | 56.6 (54.1 to 59.1) |
| Real-life accuracy (taking clinical judgement into account) | 82.5 (80.6 to 84.4) |
| Relative increase in overall accuracy when clinical judgement is applied | 1.46 (1.33 to 1.59) |
| Theoretical true positive rate (sensitivity) | 88.9 (86.5 to 91.4) |
| Real-life true positive rate (sensitivity) | 77.0 (73.6 to 80.3) |
| Theoretical false positive rate (1—specificity) | 66.1 (63.0 to 69.3) |
| Real-life false positive rate (1—specificity) | 13.6 (11.3 to 15.9) |
