Spearman’s correlation of M value with surrogate indices of insulin resistance/sensitivity
| Measures of insulin sensitivity/resistance | rho | P value |
| Lipid accumulation product index | −0.39 | <0.001 |
| Fasting glucose-insulin ratio | 0.25 | <0.01 |
| QUICKI | 0.22 | <0.01 |
| HOMA-IR | 0.06 | 0.52 |
P<0.05: statistically significant.
HOMA-IR, homeostatic model assessment of insulin resistance; QUICKI, quantitative-insulin sensitivity check index.
