Edition 5ISBN: 978-1449665494 Exercise 6
A serologic test is being devised to detect a hypothetical chronic disease.
Three hundred individuals were referred to a laboratory for testing. One hundred diagnosed cases were among the 300. A serologic test yielded 200 positives, of which one-fourth were true positives. Calculate the sensitivity, specificity, and predictive value of this test. (Hint: After setting up the appropriate 2 by 2 table, find missing data by subtraction. The numbers for the cells should then correspond to the numbers shown in Appendix 11.)
