Correlations of TROP2 and ISG15 expression in PTC from GEO Datasets

TROP2 expression	ISG15 expression		Total	P value
	High expression	Low expression
High expression	27	7	34	<0.001
Low expression	5	12	17
Total	32	19	51

High TROP2 expression group: TROP2 expression value (quantile-normalized and then log-transformed with base 10 logarithms) ≥4; low TROP2 expression group: TROP2 expression value (quantile-normalized and then log-transformed)<4; high ISG15 expression group: ISG15 expression value (quantile-normalized and then log-transformed with base 10 logarithms)≥3.1; low ISG15 expression group: ISG15 expression value (quantile-normalized and then log-transformed)< 3.1.
