DRD1 expression level and associated clinical characteristics in HCC. a DRD1 mRNA expression levels across cancers. b The DRD1 mRNA expression level was significantly decreased in primary tumour tissues compared with normal tissues. c The DRD1 mRNA expression level was decreased in HCC tissue compared with normal tissue. d–f There was no significant difference in DRD1 mRNA expression levels between patients grouped by weight, tumour grade, and sex. g, h The difference in DRD1 mRNA expression levels between patients with different tumour stages and tumour grades
