Table 1 Age and Gender of Patients in Each Group

Group	Age	Gender F/M (n)	Statistical Significance (p < 0.05)
	Average± SD
H	44.25± 6.18	9/5	b
P	45.75± 6.20	6/6	a
P + NAFLD	51.62± 5.29	7/5	a,b

Notes: n – number of patients, a - statistical significant difference of age between P + NAFLD and P groups, p < 0.05; b - statistical significant difference of age between P + NAFLD and H groups, p < 0.05.

Table 2 Average Pixel Density for Each Study Group

Group	Age	Pixel Density	Statistical Significance (p < 0.05)	Statistical Correlation r
	Average ± SD	Average ± SD
H	44.25± 6.18	72.71± 2.26	–	–
P	45.75± 6.20	50.73± 3.22	a	−0.52
P + NAFLD	51.62± 5.29	40.88 ± 1.3	b, c	−0.83

Notes: a- statistical significant difference of pixel density between P and H groups, p < 0.05; b - statistical significant difference of pixel density between P + NAFLD and P groups, p < 0.05; c - statistical significant difference of pixel density between P + NAFLD and H groups, p < 0.05; r – Pearson’s r for statistical correlation between age and pixel density.
