|Table 4: Sensitivity, specificity, predictive values, and diagnostic odds ratios using the highest values of all biomarkers within the first 24 hrs of ICU admission.|
|Sensitivity: percentage of septic patients with positive test.|
Specificity: percentage of nonseptic patients with negative test.
PPV (positive predictive value): percentage of test-positive patients with sepsis.
NPV (negative predictive value): percentage of test-negative patients without sepsis.
DOR (diagnostic odds ratio): [sensitivity/(1 − sensitivity)]/[(1 − specificity)/specificity]: the ratio of the odds of disease with a positive test relative to the odds of disease with a negative test.
