Serum levels of carbohydrate-deficient transferrin (CDT) were measured in subjects of two independent studies using two different commercial kits. The kits measure CDT either as a percentage of total transferrin (AXIS %CDT, AXIS Biochemicals AS, Norway), or as the absolute amount (CDTect, Pharmacia, Sweden). In a population of males (mean age 41 years) consisting of alcoholics, heavy, moderate and non-drinkers, a strong correlation was found between AXIS %CDT and CDTect results (r = 0.92, n = 58, P < 0.001). Sensitivity and specificity in detecting chronic alcoholic drinking of over 60 g/day were 78 and 94% for the AXIS assay, and 83 and 88% for the CDTect assay, respectively. In a population from a birth cohort study, consisting of 21-year-old males and females with less excessive alcohol consumption, the correlation between AXIS %CDT and CDTect CDT was weaker but still statistically significant (r = 0.46, n = 212, P < 0.001). In this population, with specificities > 83% in detecting alcohol consumption levels of > or = 6 drinks per week, the sensitivities were low with both CDT assays (< 43% for > or = 6 drinks per week, and < 44% for > or = 16 drinks per week). These results suggest that (a) both assays are equally effective in detecting chronic drinking over 60 g/day in older alcoholic males, and (b) both assays are similarly ineffective in detecting less excessive regular drinking in young males and females.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 December 2002.
All research outputs
#12,425,845
of 34,518,147 outputs
Outputs from Alcohol & Alcoholism
#1,024
of 2,115 outputs
Outputs of similar age
#17,647
of 41,631 outputs
Outputs of similar age from Alcohol & Alcoholism
#1
of 5 outputs
Altmetric has tracked 34,518,147 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,115 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 14.8. This one is in the 36th percentile – i.e., 36% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 41,631 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 7th percentile – i.e., 7% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
