Adult Noninvasive Fibrosis Scores in Children with NAFLD.
Figure 1.
Pediatric NAFLD Fibrosis Score Values are significantly higher in children with advanced fibrosis.
The lower boundary of the box-and-whisker plot corresponds to the 25th percentile, the line within the box to the median, and the upper boundary of the box to the 75th percentile. The whiskers extend to the most extreme data point which is no more than 1.5 times the interquartile range from the box.
Figure 2.
Performance characteristics of the Pediatric NAFLD Fibrosis Score (PNFS) in comparison to APRI, FIB-4, and NFS.
The new model (PNFS) was more accurate for predicting advanced fibrosis than APRI, FIB-4 index and NAFLD fibrosis score as assessed by the area under the ROC curve (AUROC).
Figure 3.
Bootstrap Validation of the Proposed PNFS Model.
Internal validation of the model using bootstrapping showed an area under the ROC curve (AUROC) of 0.71.
