Notably, in addition to post-MMTT HRSs for changed insulin, HDL-c or TAG levels, HRSs for changed levels of six medium- to long-chain acylcarnitines (C8, C14, C14:2, C16:1, C18:1 and C18:2OH) were inversely correlated with insulin resistance, as indicated by using homeostasis model assessment of insulin resistance (HOMA-IR) (Fig. 7; Spearman's r from –0.43 to –0.28) whereas the HRSs for changed levels of four acylcarnitines (C14, C14:2, C16:1 and C18:2OH) were positively correlated with the Matsuda index (Spearman's r from 0.26 to 0.38). Here, INS is linked to Insulin resistance.
