Vitreous Humour Carbohydrate Deficient Transferrin

Description

This data has the carbohydrate-deficient transferrin concentration in vitreous humour (VH-CDT) in 21 alcoholics and 7 non-alcoholics.

Usage

data(vhcdt.df)

Format

The data consist of a data frame with 28 observations on 7 variables.

age alc vhcdt1 vhcdt2 vhtf td th [,1]	age	integer	age in years

vhcdt1 had a detection limit of 5 micrograms per liter. Observations below this level were coded as 2.5. Similarly in the second assay a detection limit of 2.5 micrograms per liter was used. Observations below this threshold were coded as 1.125.
