Results obtained from hand-crafted radiomics.

Clinical outcome	Significant predictors	Concordance index
OS	PC2 (HR: 0.44, p-value: 0.02)	$51\%$
RFS	PC1 (HR: 1.57, p-value: 0.02), PC2 (HR: 0.37, p-value: $<0.005$), SUV (HR: 1.14, p-value: $<0.005$)	$47\%$
DC	PC1 (HR: 1.58, p-value: 0.03), PC2 (HR: 0.33, p-value: $<0.005$), SUV (HR: 1.14, p-value: $<0.005$)	$64\%$
LC	-	NA

As there is no significant predictor for the LC, Concordance index is not calculated.
