Figure 5From: Plasma metabolomics identifies lipid abnormalities linked to markers of inflammation, microbial translocation, and hepatic function in HIV patients receiving protease inhibitors Correlation matrix reveals relationships between clusters of lipids and markers of inflammation and hepatic function. The Pearson correlation matrix was constructed in R using the heatmap.2 function. Significant correlations had a −0.35> r >0.35, p<0.05, and FDR<10% (Additional file 5). Red and blue indicate positive and negative correlations, respectively (see Color Key).Back to article page
