Table 6.

Biomarkers obtained from the classification procedure with the Clinical and Anamnestic variables (first column). The second column indicates the percent of the times the variables were selected as biomarkers during the random classification procedure. The third column is the coefficient that accompany each variable in the final classification equation. The stable area under the ROC for this equation is 0.94.
