Different initial prevalence, however, was not reflected in the extent of density reduction.
With the exception of the study of Kerlikowske, the available evidence suggests that it is the extent of density at a given age, rather than the rate of change of density with increasing age, that is related to breast cancer risk (Maskarinec et al, 2006; Vachon et al, 2007a).
In a review of case-control studies using quantitative methods of determining density, odds ratios for women in the highest versus lowest extents of density (expressed as percent density) ranged from 2.1 to 6.0 [ 7].
In a review of case control studies [ 11], odds ratios for breast cancer among women with the highest versus the lowest extents of density ranged from 2.1 to 6.0.
First, studies using BI-RADS and Wolfe classification patterns capture variation in the extent of mammographic density across only four categories; therefore, studies using these categorical measures of mammographic density require larger changes to reflect a categorical change.
It was hypothesized that the extent of mammographic density is proportional to the amount of breast epithelium and that the higher breast cancer risk associated with breast density is due to a larger number of glandular cells at risk for malignant transformation [ 6, 7].
"The extent of population density and landscape domestication is extraordinary".
By quantifying the extent of movement, density of utilization, and recursive use of rangelands, we found highly diverse mobility patterns and resource-use strategies even within a single study region.
When the strongest ascending airflow of ST-Sarika eyewall was above FKS UT 12 00 (Sunset) of Oct 18, the extent of electron density profile anomaly in the F2 layer was the largest with the maximum of 0.8 ∗ 106 e/cm3, and the electrons in the F2 layer above 350-km altitude disappeared.
The inspection of current distributions after a very permissible cutoff value, of course increased the extent of current density foci, but in all cases (three bands) resulted in the same overall conclusion: not a single cytoarchitectonic area containing current foci was common to all subjects.
There are some histological features of gliomas associated with grade and prognosis, such as the extent of vascular density [ 32].
