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