What is a good NAFLD score?
The following NAFLD fibrosis score range is used to identify liver fibrosis:
| NAFLD fibrosis score | Interpretation |
|---|---|
| Less than -1.455 | Low probability of fibrosis |
| From -1.455 to 0.676 | Intermediate score |
| More than 0.676 | High probability of fibrosis at baseline |
How is NAFLD fibrosis score calculated?
NAFLD fibrosis score = -1.675 + 0.037 × age (year) + 0.094 × BMI (kg/m2) + 1.13 × IFG/diabetes (yes = 1, no = 0) + 0.99 × AST/ALT ratio – 0.013 × platelet count (×109/L) – 0.66 × albumin (g/dL)[9]. In this study, the NFS was used to classify advanced liver fibrosis into 2 categories[9].
How accurate is the NAFLD fibrosis score?
By applying the high cutoff score (0.676), the presence of advanced fibrosis could be diagnosed with high accuracy (positive predictive value of 90% and 82% in the estimation and validation groups, respectively).
What does NAFLD fibrosis score mean?
The NAFLD fibrosis score (NFS) was used to separate NAFLD patients with and without advanced liver fibrosis. We used the NFS score to classify the probability of fibrosis as < -1.5 for low probability, > -1.5 to < 0.67 for intermediate probability, and > 0.67 for high probability.
How do you read a NAFLD score?
Scores ≤ -1.455 to ≤ 0.675: indeterminate Scores > 0.675 suggest a high risk of fibrosis (positive predictive value of 82%-90%). (The result should be entered into EMIS Web using the term ‘NAFLD fibrosis score’) Patients with high scores should be referred to liver clinic for further investigations.
What does fibrosis score of F4 mean?
A fibrosis score of F4 ( 14 kPa or higher) means late-stage scarring or cirrhosis, where the scarring is permanent and the damage is irreversible.
What is NAFLD Fibrosis Score?
NAFLD (Non-Alcoholic Fatty Liver Disease) Fibrosis Score. Patients who have been identified to have NAFLD. Nonalcoholic fatty liver disease (NAFLD) is now the leading cause of chronic liver disease in the world. Many NAFLD patients will have little progression in their disease, however a subset will progress to liver fibrosis and cirrhosis.
Does NAFLD reduce the need for liver biopsies?
The NAFLD can reduce liver biopsies in those patients predicted to have a low risk of fibrosis by their score: “a liver biopsy to determine severity of fibrosis would be required in only 25% of patients with NAFLD, that is, those identified as ‘indeterminate’.”
Is there a scoring system for nonalcoholic fatty liver disease (NAFLD)?
We constructed and validated a scoring system consisting of routinely measured and readily available clinical and laboratory data to separate NAFLD patients with and without advanced fibrosis. A total of 733 patients with NAFLD confirmed by liver biopsy were divided into 2 groups to construct (n = 480) and validate (n = 253) a scoring system.
What is the relationship between nonalcoholic fatty liver disease and advanced fibrosis?
Patients with nonalcoholic fatty liver disease (NAFLD) and advanced liver fibrosis are at the highest risk for progressing to end-stage liver disease. We constructed and validated a scoring system consisting of routinely measured and readily available clinical and laboratory data to separate NAFLD patients with and without advanced fibrosis.
