Correct Answer is B
Explanation
A. Number of true negatives / (true negatives + false positives): This formula is used to calculate specificity, not incidence.
B. Number of new cases in a period of time / total population × base multiple of 10: Incidence rate measures the number of new cases of a disease occurring in a population during a specific period. It is expressed per a base population size (e.g., per 1,000 or 100,000 people) to allow for comparisons across different populations.
C. Number of true positives / (true positives + false negatives): This formula is used to calculate sensitivity, not incidence.
D. Number of new cases + number of old cases in a period of time / total population × base multiple of 10: This describes prevalence, which includes both new and existing cases, not incidence.
