Primary | Diagnostic performance | The comparison of the results obtained by the mathematical analysis of the infrared spectra with those obtained by the reference method on histological samples from liver biopsies will allow to classify the results in true-positive, false-positive, true-negative and false-negative. The diagnostic performance of the signature will be evaluated by calculating the sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio values. |
