Correlations of mRNA levels of three key enzymes in BCAA degradation with insulin sensitivity (Matsuda ISI), early-phase insulin
secretion (InsAUC0–30/GluAUC0–30), FPG and 2hPG. r’, partial Pearson correlation coefficient controlled for Matsuda ISI. *P < 0.05. **P < 1 × 10−4. ***P < 1 × 10−10. The solid line indicates the linear regression line for the unadjusted variable, and the dotted line indicates linear regression
line for the variable adjusted for Matsuda ISI.
