XIAP and TGF-β experssion in ESCC tissues. a Scatterplots with fitting line show positive correlation between XIAP and TGF-β expression (IOD) in ESCC tissues. Spearman correlation provides correlation coefficient (r) and p value. b Representative image of ESCC tissues in XIAP and TGF-β group by IHC staining (×200)
