- Given the following data:
Number of patients = 3,293
Number of patients who had a positivetest result and had the disease = 2,184
Number of patients who had a negativetest, and did not have the disease = 997
Number of patients who had a positivetest result, but did not have the disease = 55
Number of patients who had a negativetest result, but who had the disease = 57
