LINC01138 is associated with clinical outcomes in patients with HCC. a The flow chart for selecting candidate lincRNAs in HCC; four lincRNAs were identified for further study. b The copy numbers of LINC01138 were determined in 72 pairs of HCC tissues and adjacent normal tissues using qPCR. c Fold-change of LINC01138 copy number variations in 72 paired tissues (deletion, blue; no-change, yellow; amplification, red.). d The RNA levels of LINC01138 were quantified in 120 pairs of HCC tissues and adjacent normal tissues using qPCR. e Fold-changes of expression of LINC01138 in 120 paired tissues (downexpression, blue; no-change, yellow; upexpression, red.). f Clinical significance of LINC01138 in patients with HCC; high LINC01138 expression positively correlated with tumour size (≥5 cm), AFP (>200 ng/ml) and HBsAg-positive patients. g Kaplan–Meier analyses of the correlation between LINC01138 RNA levels and the overall survival in 120 patients with HCC. Patients were stratified for the analysis by the median value. Values are expressed as the median with interquartile range in b, d, f
