Alcoholic Liver Disease | Logistic Regression Function

 

Parameters:

(1) hemoglobin as percent of normal

(2) serum albumin in g/dL

(3) encephalopathy score

 

logistic regression score =

= ((-0.025) * (hemoglobin as percent normal)) - (1.56 * (albumin in g/dL)) + (1.03 * (encephalopathy score)) + 6.0

 

where:

• Hemoglobin is expressed as a whole number.

• The "normal" hemoglobin used for calculation is lower limit of reference range; an alternative would be the mean of the reference range.

• The encephalopathy score is 1, 2 or 3.

 

Interpretation

Score	% mortality
-5.4 to -4.0	4%
-3.9 to -2.6	5%
-2.5 to -1.2	11%
-1.1 to 0.2	33%
0.3 - 1.6	80%
1.7 - 3.0	100%

 

where:

• The percent mortality is estimated from Figure 6, page 902.
