We found epicardial adipocytes in CAD patients have larger standard deviation of area-equivalent circular diameter, larger relative size variation, and higher population percentage of small-sized ones (AECD < 40 μm) than those in no-risk-factor patients.
> There was little difference between the cases and controls with respect to nuclear morphometric features including mean area, standard deviation (SD) of area, perimeter, diameter, shortest axis, and longest axis, as well as such shape factors as Form_PE, Form_NCI, contour, and roundness (Table 2).
Accuracy here is defined as the deviation of the area of the digitised image from the actual area of the real particle.
STD of the region area [ 21 ]: the CAD computes the standard deviation of the region area for all the labeled regions contained on the entire image.
In terms of the accuracy of retention time and peak area, both the mean of retention time variation and the mean of relative standard deviation of peak area of the aligned peaks are smaller than the corresponding values obtained by the variation window approach in all three sample groups (Table 1).
The standard error of the mean (SEM) was calculated as the standard deviation of the area percentage divided by the square root of the number of images for each quantification.
The mean and standard deviation of suitable area (measured as the number of 5° cells, which is roughly equivalent to 58,000 km2) were then calculated for each species.
Mean and standard deviation of nuclear area, perimeter, diameter, shortest axis, longest axis, and axis ratio were calculated, as well as different shape factors.
