negative predictive value (NPV), false positive probability, and false negative probability are row or column percentages of the 2×2 tableNote. Beginning in SAS®9.4M6 (TS1M6), point estimates and confidence intervals for sensitivity, specificity, PPV, and NPV are available in PROC FREQ (and...
High-Sensitivity Troponin in the Evaluation of Patients With Acute Coronary Syndrome; hs-cTnI = high-sensitivity cardiac troponin I; hs-cTnT = high-sensitivity cardiac troponin T; MI = myocardial infarction; NA = not applicable; NPV = negative predictive value; PPV = positive predictive value. ...
a less than 10% chance of having an infection. This infection probability score was shown to be higher in patients with definite or probable infection than in those with unlikely or no infection and had a positive predictive value of 80% and a negative predictive value of 86% for infection....
Sensitivity, specificity, positive predictive value, and negative predictive value of the different imaging modal- ities, scoring, and reference standard are shown in Table 2. By sensitive reading and using a reference standard of 6 months, the sensitivity of ceCT, PET/non-ceCT, and PET/ceCT ...
The sensitivity and negative predictive value were 83.3 and 97.2% when 6 months, 60.0 and 89.9% when 12 months, and 37.5 and 72.2% when 30 months follow-up were used as reference standard, respectively. This is comparable with reported studies with similar reference standards. This critical ...
