AgNOR parameters

nornbc_m

Mean value of the corrected number of the AgNORs per cell nucleus (the AgNORs lying very close together in the cell nucleus are recorded as a conglomerate and counted accordingly)

nor_k1

mean number (percentage) of nuclei contained in 1 AgNOR

nor_k2

mean number (percentage) of nuclei contained in 2 AgNORs

nor_k4

mean number (percentage) of nuclei contained in 4 AgNORs

nor_k5

mean number (percentage) of nuclei contained in 5 AgNORs

nor_k6

mean number (percentage) of nuclei contained in 6 AgNORs

nor_k7

mean number (percentage) of nuclei contained in 7 AgNORs

nor_k8

mean number (percentage) of nuclei contained in 8 AgNORs

snar_r_v

Standard deviations of the surface of the single AgNOR in relation to the total surface of the AgNORs per cell nucleus in μm² per mille

center_v

Standard deviation of the position of the AgNORs located in the centre of the cell nucleus

cent_r_v

Standard deviation of proportion of AgNORs in a central position

bord_r_v

Standard deviation of the proportion of the AgNORs located in the defined, peripheral zone in the cell nucleus

locat_v

Position of the NORs

mnrat2_m

Mean ratio between largest AgNOR and total AgNOR area size per cell nucleus in per mille
