Brain uptake was rather stable with a variability ranging from 6%to16%6%, whereas the variability of 18F-FDG concentrations in blood and the Harderian gland was in a range of 20%to40%0%.
Contradictory to accuracy, a high variability (range from 49 140 minutes) and a learning curve have been observed concerning the operating time.
In a retrospective study of a random sample of screening mammograms, Elmore et al (2002) found a large variability range among community radiologists regarding false-positive rates, which was not eliminated after adjustment for patient, radiologist, and testing characteristics.
Moreover, LCA results available for EGS case studies cover a fairly high variability range.
Out of the 15 datasets studied, only two (34, 35) had tabulated Cmax and Tmax data for the i.v. study with a measure of variability (range or standard deviation) available.
For Lu, the mean RE is barely 1.1 with a narrow inter-patient variability range (∼0.05), while for Y it is about 1.5 with a greater variability (∼0.30).
Regarding specificity of anti-CCP2, some studies have shown a wide variability ranging from 40%to83%3% [ 26, 27], the frequency of negatives being a limitation to establish the diagnosis in RA.
Imaprax-G ICCs show a high variability ranging from 0.33 for chronic to 0.84 for subacute patient group.
Currently, median survival approaches 6 years, but there is a wide variability, ranging from less than 1 year to more than 2 decades.
Expression levels, however, displayed a high variability ranging from abundant presence in the liver, stomach and gall bladder to barely detectable, such as in the thymus.
