Tumor SQSTM1 Expression Level in Relation to the Pathological Grade of Tumors.

Tumor SQSTM1 expression	Pathological grade of tumors
	Grade I (n = 9)	Grade II (n = 31)	Grade III (n = 10)
Range	18–20	15–31	35–42
Median	20.00	28.00	39.00
Mean ± SD	19.33 ± 1.000	26.58 ± 3.566	38.70 ± 2.263
P Value	P < 0.001∗
Significance between groups	P1 = 0.005∗, P2 < 0.001∗, P3 < 0.001∗
Test of Significance	H = 33.789

H: Kruskal–Wallis test, pairwise comparison between each two groups was done using post hoc test (Dunn’s for multiple comparisons test).

P: P value for comparing between the different studied groups.

P₁: P value for comparing between patients with grade I and grade II.

P₂: P value for comparing between patients with grade I and grade III.

P₃: P value for comparing between patients with grade II and grade III.

∗: Statistically significant at P ≤ 0.05.
