S100 calcium binding protein A6 and associated long noncoding ribonucleic acids as biomarkers in the diagnosis and staging of primary biliary cholangitis

Figure 9 Correlation analysis of biomarkers and clinical serological indices. A: The positive correlation between relative expression of s100 calcium binding protein A6 protein messenger ribonucleic acid and log10 LINC00472, r = 0.683, P < 0.0001; B: The positive correlation between relative expression of log10 LINC00472 and serum level of collagen type IV, r = 0.482, P < 0.0001; C: The positive correlation between serum level of collagen type IV and relative expression of s100 calcium binding protein A6 protein messenger ribonucleic acid, r = 0.732, P < 0.0001.
