Calculates the positive predictive value and negative predictive value for test results using specified prevalence values.
Positive predictive value = sensitivity × prevalence / (sensitivity × prevalence + (1 − prevalence) × (1 − specificity))
Negative predictive value = specificity × (1 – prevalence) / (specificity × (1 – prevalence) + prevalence × (1 – sensitivity))
Negative predictive value = specificity × (1 – prevalence) / (specificity × (1 – prevalence) + prevalence × (1 – sensitivity))
| Positive predictive value | % |
| Negative Predictive Value | % |
