| CD55 | TLR4 | CD55 + TLR4 (LD) | CD55 + TLR4 (DF) | |
| AUC ± SE | 0.85 ± 0.004 | 0.95 ± 0.004 | 0.96 ± 0.004 | 0.96 ± 0.003 |
| (95% CI) | 0.84 - 0.86 | 0.94 - 0.95 | 0.96 - 0.97 | 0.96 - 0.97 |
| Sensitivity | 0.79 | 0.79 | 0.82 | 0.85 |
| Specificity | 0.93 | 0.96 | 1.00 | 0.88 |
Standard errors (SE) of AUC values were calculated from the 10 replicates of the cross validation procedure. Confidence intervals (CI) were calculated using exact binomial data (AUC ± 1.96 SE).
LD = combination model linear discriminant method, DF = combination model distribution free method.
