*UBR5^Low expression: H-scores of UBR5 < 130; UBR5^High expression: H-scores of UBR5 ≥ 130

**Statistical significance was calculated by Chi squared test or Fisher’s exact test for categorical/binary measures

P-value for this item is less than 0.05 and there is a statistical difference between the corresponding two groups of data
