Key result
Mathematical models incorporating waist circumference alongside fasting insulin (R2=0.77), serum triglycerides (R2=0.65), or subscapularis skin fold (R2=0.64) reliably predicted insulin sensitivity.
Why the study?
Can simple mathematical models accurately predict insulin sensitivity in women with PCOS?
Cross-Sectional (n=153)
Can simple mathematical models accurately predict insulin sensitivity in women with PCOS?
Effect estimate: R2 = 0.77
Simple mathematical models using waist circumference combined with insulin, triglycerides, or skin folds can reliably predict insulin resistance in women with PCOS, offering an inexpensive screening tool.

May enable low-cost insulin sensitivity screening in PCOS; leaves open prospective validation before practice change.
Gianluca Gennarelli (2000) conducted a cross-sectional in Polycystic ovary syndrome (PCOS) (n=153). Clinical and biochemical prediction models vs. Euglycaemic hyperinsulinaemic clamp was evaluated on Prediction of insulin sensitivity (R2 = 0.77). Mathematical models incorporating waist circumference alongside fasting insulin (R2=0.77), serum triglycerides (R2=0.65), or subscapularis skin fold (R2=0.64) reliably predicted insulin sensitivity.
