Table 2 Formulae for evaluation of DIGFA
| Index | Formulae | Index | Formulae |
| Sensitivity | a/(a+c) | Specificity | d/(b+d) |
| Positive predictive value | a/(a+b) | Negative predictive value | d/(c+d) |
| Accuracy | (a+d)/N | Youden index | [a/(a+c)]/[d/(b+d-1)] |
| Positive likelihood ratio | [a/(a+c)]/[b/(b+d)] | Negative Likelihood ratio | [c/(a+c)]/[d/(b+d)] |
