Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Overall accuracy of "significant coronary artery disease (CAD)" according to non-invasive imaging modality
Tidsramme: baseline
|
The overall accuracy is calculated as the probability that a subject is correctly classified (presence of significant CAD or not) by non-invasive imaging modality.
The standard of truth is presence of significant CAD or not according to the invasive fractional flow reserve (FFR)
|
baseline
|
|
Sensitivity of "significant CAD" according to non-invasive imaging modality
Tidsramme: baseline
|
The sensitivity is calculated as the probability that a subject with presence of significant CAD according to FFR is correctly identified as such by non-invasive imaging modality
|
baseline
|
|
Specificity of "significant CAD" according to non-invasive imaging modality
Tidsramme: baseline
|
The specificity is calculated as the probability that a subject with absence of significant CAD according to FFR is correctly identified as such by non-invasive imaging modality
|
baseline
|
|
Positive predictive value of "significant CAD" according to non-invasive imaging modality
Tidsramme: baseline
|
The positive predictive value is calculated as the probability that a subject with presence of significant CAD according to non-invasive imaging modality truly have significant CAD according to FFR
|
baseline
|
|
Negative predictive value of "significant CAD" according to non-invasive imaging modality
Tidsramme: Baseline
|
The negative predictive value is calculated as the probability that a subject with absence of significant CAD according to non-invasive imaging modality truly does not have significant CAD according to FFR
