Distribution of patients between the grading groups given in Table 1.: A. Group A, B. Group B. The value of the discriminant function for each patient is determined by a weighted combination of image features significantly associated (p < 0.001) with the characteristics of the grading groups, factors that dealt with sum of pixel intensities (sum density) and changes in spatial arrangement (diagonal moment and product moment).
