| Sub-samples of participants (n) | Sensitivity % [95% CI] | Specificity % [95% CI] | Positive, predictive value, % [95% CI] | Negative, predictive value, % [95% CI] |
|---|---|---|---|---|
| With cognitive impairment, (42) | 71.4 [29.0-96.3] | 42.9 [26.3-60.6] | 20.0 [6.8-40.7] | 88.2 [63.6-98.5] |
| Without cognitive impairment, (71) | 75.0 [19.4-99.4] | 79.1 [67.4-88.1] | 17.6 [3.8-43.4] | 98.1 [90.1-100.0] |
| With psychomotor retardation, (46) | 70.0 [34.8-93.3] | 44.4 [27.9-61.9] | 25.9 [11.1-46.3] | 84.2 [60.4-98.9] |
| Patients (hospital), (73) | 70.0 [34.8-93.3] | 81.0 [69.1-89.8] | 36.8 [16.3-61.6] | 94.4 [84.6-98.8] |
| Residents (nursing home), (40) | 100.0 [2.5-100.0] | 43.6 [27.8-60.4] | 4.3 [0.1-21.9] | 100.0 [80.5-100.0] |
CI: Confidence interval.
