Calculate sensitivity, specificity, PPV, and NPV for a diagnostic test given the following data: TP=744, FP=21, FN=31, TN=1829.

First, let's extract the given data: Number of patients with the disease = 775; Number of patients with the disease who reported symptoms (True Positives, TP) = 744; Number of patients without the disease = 1850; Number of patients without the disease who reported symptoms (False Positives, FP) = 21 From this, we can calculate: Number of patients with the disease who did not report symptoms (False Negatives, FN) = 775 − 744 = 31 Number of patients *

Solved: Calculate sensitivity, specificity, PPV, and NPV…

First, let's extract the given data:

Number of patients with the disease = 775
Number of patients with the disease who reported symptoms (True Positives, TP) = 744
Number of patients without the disease = 1850
Number of patients without the disease who reported symptoms (False Positives, FP) = 21

From this, we can calculate:

Number of patients with the disease who did not report symptoms (False Negatives, FN) = $775 - 744 = 31$
Number of patients *

Calculate sensitivity, specificity, PPV, and NPV for a diagnostic test given the following data: TP=744, FP=21, FN=31, TN=1829.
