**Sensitivity & specificity YouTube**

This approach can be overwhelming to non-math types, so this demonstration goes through the steps of assuming a virtual population, then filling in a 2x2 table based on the population and given values of Sensitivity, Specificity, and Prevalence. PPV and NPV are then computed from this table. This approach is more intuitive to many people.... Sensitivity and specificity are measures of a test's ability to correctly classify a person as having a disease or not having a disease. Sensitivity refers to a test's ability to designate an individual with disease as positive. A highly sensitive test means that there are few false negative results, and thus fewer cases of disease are missed. The specificity of a test is its ability to

**PROC FREQ Analysis of a 2x2 Contingency Table**

Set up the 2x2 table to calculate positive predictive value. (Hint: Use prevalence for determining marginal total of subjects who have the disease, TP+FN . Use this information and formulas for sensitivity and specificity to determine TP, FN, FP and TN) .... An assay's analytical sensitivity and analytical specificity are distinct from that assay's clinical diagnostic sensitivity and diagnostic specificity. “Diagnostic sensitivity” is the percentage of persons who have a given disorder who are identified by the assay as positive for the disorder. High analytical sensitivity does not guarantee acceptable diagnostic sensitivity. “Diagnostic

**Sensitivity and Specificity A Caries Example**

Calculate sensitivity, specificity, and positive predictive value of this screening test. Show how you set up the equations. Sensitivity: probability that a test result will be positive when the disease is present (true positive rate, expressed as a percentage)... - Pictorial representation of the true positive (sensitivity) rate versus the false positive (1-specificity) rate of a given test at different cut-off points - Displays how the sensitivity and specificity of a certain test changes as the cut-point changes

- (hint: draw a new 2x2 table and write the new column totals for the Clinician Gold Standard using the new "true" population prevalence of 1%, given a total N=1000 Then use the specificity and sensitivity proportions you calculated previously to fill in the rest of the 2x2 table.) NOTE: ONLY USE THE SENSITIVITY AND SPECIFICITY VALUES ROUNDED TO 2 DECIMAL PLACES THAT APPEAR IN THE …
