Fig. 1: PAARH was highly expressed and correlated with poor survival in HCC.

a PAARH (CMB9-22P13.1) expression in 369 HCC tissues and 50 liver tissues according to TCGA LIHC dataset, analyzed by GEPIA. b The correlation between PAARH (CMB9-22P13.1) expression and overall survival according to TCGA LIHC dataset, analyzed by GEPIA. c The correlation between PAARH (CMB9-22P13.1) expression and disease-free survival according to TCGA LIHC dataset, analyzed by GEPIA. d PAARH expression in 72 pairs of HCC tissues and adjacent noncancerous liver tissues was measured by qRT-PCR. ****p < 0.0001 by Wilcoxon matched-pairs signed rank test. e Kaplan–Meier survival analysis of the correlation between PAARH expression and overall survival in our HCC cohort. n = 72, p = 0.0289, HR = 2.019 by log-rank test. f Kaplan–Meier survival analysis of the correlation between PAARH expression and disease-free survival in our HCC cohort. n = 72, p = 0.0264, HR = 1.883 by log-rank test.
