The multiple logistic model contains 15 expressed genes, with controlling for age, gender, and smoking status. The other seven molecular markers (CPEB4, EXT2, IRF4, MCM4, MMD, NF1, STAT2, WEE1, and ZNF264) were not significantly associated.
The performance of this model is presented as the sensitivity and specificity depending on the cut-off value chosen:
cut-off value =0.391, Sensitivity = 0.661, Specificity = 0.952
cut-off value =0.224, Sensitivity = 0.763, Specificity = 0.900
cut-off value =0.172, Sensitivity = 0.763, Specificity = 0.855
cut-off value =0.127, Sensitivity = 0.797, Specificity = 0.800
cut-off value =0.100, Sensitivity = 0.847, Specificity = 0.735
