  1. *In model 1, hazard ratios were calculated with the use of Cox regression after adjustment for age (<40, 40 to 49, 50 to 59, or ≥60 years), alcohol consumption (none, 0.1 to 6.9, or ≥7.0 g/day), regional lymph node metastasis (negative or positive), tumor size (<2 cm or ≥2 cm), and chemotherapy (yes or no).
  2. †Model 2 was adjusted for the factors in Model 1 plus adiponectin and HOMA-IR.
  3. ‡High blood pressure was defined if systolic/diastolic blood pressure ≥130/85 mmHg or receiving drug treatment.
  4. §Obesity was defined if Body Mass Index ≥25 kg/m2.
  5. Hyperglycemia was defined as fasting glucose ≥100 mg/dl or receiving drug treatment.
  6. ¶Decreased HDL cholesterol as defined if HDL cholesterol <50 mg/dl or receiving drug treatment.
  7. **Elevated triglycerides was defined if triglycerides ≥150 mg/dl or receiving drug treatment
  8. ††P-value for trend was calculated to check the trend of the hazard ratio for breast cancer recurrence according to the number of components of metabolic syndrome.
