aSensitivity = [true positives/(true positives + false negatives)] × 100
-
bSpecificity = [true negatives/(true negatives + false positives)] × 100
-
cCorrelation = [number of samples positive by both methods + number of samples negative by both methods]/[total number of samples] × 100
-
dLikelihood ratio for positive result = sensitivity/1 − specificity
-
eLikelihood ratio for negative result = specificity/1 − sensitivity
