Slide: 23 of 50

Evaluation of Diagnostic Methods (2 of 2)

Comparative analyses included:

Sensitivity: The probability of a true positive result when used on an affected population

Specificity: The probability of a true negative result when used on a nonaffected population

Positive Predictive Value (PPV): The ratio of the number of true positives to the total number of positive test outcomes

Positive Likelihood Ratio: The ratio of the probability of a true positive (the sensitivity) to the probability of a false positive (1-specificity). The larger the positive likelihood ratio, the more useful the test:

1  No difference

1–2  Minimal

2–5  Small

5–10  Moderate

>10  Large, conclusive
