Question
How does an increase in disease prevalence within a study population affect the Positive Predictive Value (PPV) of a diagnostic test, assuming sensitivity and specificity remain constant?
Correct Answer
Option A is the correct answer.
Detailed Explanation
PPV is dependent on prevalence; as the true disease prevalence rises in a population, a positive test result is more likely to represent a true positive.
