Two new tests (A and B) have been developed to diagnose gout. The following tables provide information on the number of individuals testing positive or negative and their true status:
Calculate the sensitivity, specificity, and positive predictive values for both tests.
b) Imagine a situation where the consequences of false negative test results are worse than a false positive test. For example, patients that have gout but test negative may not be treated properly and develop other complications. Which test would you use in this situation? Why?
