Question

Quizplus · Accepted Answer

The positive predictive value (PPV) is calculated using the formula: PPV = (True Positives) / (True Positives + False Positives). Without additional data on sensitivity, specificity, or prevalence, we cannot calculate the exact PPV. However, given the choices, 28.6% is a plausible estimate for a condition with a relatively low incidence like 4 per 1000.
