BARD Score for assessing Fibrosis in NAFLD

Description

By using a patient's bmi, lab values of aspartate transferae, alanine transferase, and whether they have type 2 diabetes, calculate the patient's risk for fibrosis, especially if they have diagnosed or suspected NAFLD. BARD score from 0-1 is low risk of fibrosis and a score from 2-4 is high risk of fibrosis. Created by Harrison et al. 2008. Validated by Ruffillo et al. (2011) and Raszeja-wyszomirska et al. (2010).

Usage

bard_score(bmi, ast, alt, diabetes)

Arguments

bmi

Numeric value of bmi (kg/m^2).

ast

alt

Numeric value of alanine transferase (U/L).

diabetes

Numeric value of type 2 diabetes mellitus status yes = 1, no = 0.

Value

A numeric value/vector with predicted BARD score.
