KTN1 and hepatocellular carcinoma: A moderate ability of KTN1 to differentiate HCC from non-HCC tissue was detected from the SROC curve (Figure S3A), with a sensitivity (Figure S3B), specificity (Figure S3C), positive likelihood ratio (Figure S3D), and negative likelihood ratio (Figure S3E) of 44% [0.26, 0.63], 81% [0.67, 0.90], 2.36 [1.78, 3.12], and 0.69 [0.55, 0.86], respectively, implying its general accuracy.
