TM4SF4 and hepatocellular carcinoma: Three datasets contained matched NTL cases, i.e., CNHPP (n = 35 for each HCC and NTL group), GSE14520 (NTL n = 220; HCC n = 225), and CHCC (n = 166 for each HCC and NTL group), and hence they were utilized for comparison of TM4SF4 expression between both groups.
