- A non-parametric analysis was performed;
- Abbreviations: Overall: all dilution steps were analysed together; AUC: area under the ROC-curve; LR+/LR-: Positive and negative likelihood ration; theta0/d0: co-ordinates at cut-off point of equivalence with specificity = sensitivity = theta0; IR: intermediate range, VRP: valid range proportion
