Corticosteroid therapy or pentoxifylline have been used with mixed results for patients whose increased mortality is indicated with a value greater than 32. [ 5 ] To calculate Maddrey discriminant function using SI units, such as micromoles per litre, divide bilirubin value by 17.
Ordinary least squares regression of Okun's law.Since the regression line does not miss any of the points by very much, the R 2 of the regression is relatively high.. In statistics, the coefficient of determination, denoted R 2 or r 2 and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
The Lille Model is a medical modeling tool for predicting mortality in patients with alcoholic hepatitis who are not responding to steroid therapy. The model risk stratifies patients who have been receiving steroid treatment for seven days to predict who will improve and who should be considered for alternative treatment options including early referral for transplant.
The Model for End-Stage Liver Disease, or MELD, is a scoring system for assessing the severity of chronic liver disease.It was initially developed to predict mortality within three months of surgery in patients who had undergone a transjugular intrahepatic portosystemic shunt (TIPS) procedure, [1] and was subsequently found to be useful in determining prognosis and prioritizing for receipt of ...
is the average number of people infected from one other person. For example, Ebola has an of two, so on average, a person who has Ebola will pass it on to two other people.. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the ...
Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
R-value (soils) in geotechnical engineering, the stability of soils and aggregates for pavement construction; R-factor (crystallography), a measure of the agreement between the crystallographic model and the diffraction data; R 0 or R number, the basic reproduction number in epidemiology; In computer science, a pure value which cannot be ...
In medicine, specifically gastroenterology, the Child–Pugh score (or the Child–Turcotte–Pugh (CTP) score or Child Criteria) is used to assess the prognosis of chronic liver disease, mainly cirrhosis.
