Table 3 Analysis and comparison of area under receiver operating characteristic curve

From: Low serum ficolin-3 levels are associated with severity and poor outcome in traumatic brain injury

Variables 1-week mortality prediction 6-month mortality prediction 6-month functional outcome prediction
AUC (95 % CI) P value AUC (95 % CI) P value AUC (95 % CI) P value
GCS scores 0.883 (0.814–0.933) Ref. 0.875 (0.805–0.927) Ref. 0.872 (0.802–0.925) Ref.
Ficolin-3 levels 0.836 (0.760–0.896) 0.305 0.818 (0.740–0.881) 0.186 0.815 (0.736–0.878) 0.196
GCS scores + ficolin-3 levels 0.915 (0.853–0.957) 0.294 0.904 (0.839–0.949) 0.232 0.900 (0.835–0.946) 0.207
  1. A combined logistic-regression model was configured to estimate the additive benefit of ficolin-3 to GCS score. Comparisons of AUCs were performed using z test. GCS score + ficolin-3 level indicates the combined use of GCS score and ficolin-3 level to predict prognosis
