Detection performance as a function of accuracy at the lowest concentration detected by each dog.
| Dog | Lowest concentration of amyl acetate: mineral oil detected | Accuracy (%) |
|---|---|---|
| Dog 1 | 1: 45,000,000 | 81.71 |
| Dog 2 | 1: 45,000,000 | 87.50 |
| Dog 3 | 1: 70,000,000 | 96.49 |
| Dog 4 | 1: 70,000,000 | 84.73 |
| Dog 5 | 1: 100,000,000 | 90.90 |
| Dog 6 | 1: 100,000,000 | 83.11 |
| Dog 7 | 1: 1,500,000,000 | 87.05 |
| Dog 8 | 1: 1,500,000,000 | 92.86 |
| Dog 9 | 1: 1,000,000,000 | 83.33 |
| Dog 10 | 1: 45,000,000 | 86.59 |
The accuracy was calculated as the proportion of correct assessments (true positive + true negative) over total number of assessment (true positive + true negative + false positive + false negative) of the test data (47).
