Fig. 3From: CD63-positive extracellular vesicles are potential diagnostic biomarkers of pancreatic ductal adenocarcinomaCorrelation analysis between EVs and CA19-9. Spearman’s rank correlation coefficient tests between CD41+-EVs and CD61+-EVs (a), CD41+-EVs and CD63+-EVs (b), CD63+-EVs and CD61+-EVs (c), CD63+-EVs and CA19-9 (d), CD41+-EVs and CA19-9 (e), CD61+-EVs, and CA19-9 (f) were shown. ρ and p-values are indicated in the figureBack to article page
