The table shows the correlation analysis between metabolic health parameters and physiological parameters and demonstrates a strong correlation of HOMA-IR and QUICKI with body weights, pancreas weights, plasma and tissue insulin levels, and plasma and tissue TBARS levels ( ). The table also shows the correlation analysis for other metabolic and physiological parameters ( ). FBG: fasting blood glucose, FPI: fasting plasma insulin, HOMA-IR: homeostasis model of assessment for insulin, QUICKI: quantitative insulin sensitivity check index, TBARS: thiobarbituric acid reacting species.  
**Correlation is significant at the 0.01 level (2-tailed).
*Correlation is significant at the 0.05 level (2-tailed).
