Heat map showing positive (in red), and negative (in blue) partial correlation (adjusting for sex, age, BMI and center) of the lipoprotein insulin resistance (LPIR) score and its components scores with select metabolites (those with LPIR correlation coefficient less than − 0.3 or more than 0.3 (n = 139)). Metabolites were characterized according to their molecular structure. Each line belongs to one metabolite. Abbreviations: Ce = ceramide, CE = cholesteryl ester, DG = diglycerides, PC = phosphatidylcholine, PE = phosphoethanolamine, PI = phosphatidylinositol, SM = sphingomyelin, TG = triglycerides
