  1. Tests for linear trend were conducted by assigning median values of each quartile of TyG-BMI index as a continuous variable in the models
  2. Crude model: did not adjust other covariants
  3. Minimally adjusted model: adjusted age; AMH; BMI; AFC
  4. Fully adjusted model: adjusted age; Basal FSH; Basal E2; Basal LH; AMH; AFC; Total Gn dose; Duration of Gn;
  5. E2 on triggering day; P on triggering day. CI, confidence interval; Ref, reference
  6. Abbreviations: TyG-BMI index, triglyceride glucose-body mass index
