Exercise Tolerance Test: a comparison between true positive
and false positive test results.
Officers patrolling boxer Anthony Joshua's world heavyweight title fight with Carlos Takam in Cardiff recorded five true positives
compared to 46 false positives, while there were no recordings of either kind when Prince Harry and Meghan Markle visited the city in January.

A patient-based true positive
identification was defined as any mpMRI detected lesion in a patient with pathologically verified recurrence.
Obtained results of the developed individual and integrated classification models are compared using accuracy, true positive
rate, precision, F-measure, kappa statistic, mean absolute error, and root mean squared error.
While 211 patients had a positive cotinine assays ([greater than or equal to]500 ng/mL) and reported tobacco use (true positive
), 202 had a negative cotinine assay and reported no tobacco use (true negative); (sensitivity: 87.2%, specificity: 89.0%).
Precision value is evaluated according to the feature classification at true positive
prediction; false positive.
Out of 56 cases of clinically diagnosed potentially malignant lesions, VELscope detected overall 39 cases as true positive
, 4 cases as true negative, 1 case as false positive, and 12 cases as false negative with sensitivity of 76.6% and specificity of 80% with positive predictive value (PPV) as 97.5% and negative predictive value (NPV) as 25%.
The true positive
and false negative test results in fascioliasis cases of animals are provided in Figure 1.
In rough mathematical terms, the ROC curve is simply a graph that illustrates the relationship between the true positive
rate and the false positive rate.
The PPV can be thought of as the likelihood that a positive test result means that the sample examined is a true positive
, or the fraction of true positives
over assay positive calls in a set.
