Question
Sampleton is a small rural village in rural Brazil that has a population of 5,000 with high rates of heart disease. To identify people at risk of developing heart disease, public health workers conduct a village-wide cholesterol screening to identify everyone with high cholesterol - a risk factor for heart disease. They find that 25% of the population has "high" total cholesterol values, defined as 240mg/dL and above. If the sensitivity of the test is 90%, how many false negatives would there be in this population? [Round to the nearest whole number. Hint: Draw your square/matrix and figure out which information goes where.] O1125 3375 O 125 4500 Test Sensitivity & Specificity e A True Positive (TP) Disease C False Negative (FN) Sensitivity TP A TP + FN A+C = All diseased patients (A + C) B False Positive (FP) D True Negative (TN) Specificity TN B FP+TN B+D = All non-diseased patients (B+ D) Predictive Value Positive Predictive Value (PPV) TP A TP+FP A+B = Negative Predictive Value (NPV) TN FN+TN = D C+D Total Positive Results (A + B) Total Negative Results (C+D)
