Abbreviation: TSH: thyroid-stimulating hormone.
Notes: Clinical pregnancy rate: number of patients with embryos exhibiting a heartbeat on transvaginal ultrasound (TVUS) 4 to 5 weeks after embryo transfer divided by the number of cycles × 100.
Miscarriage rate: number of patients who miscarried divided by the number of patients who had clinical pregnancy × 100.
Live birth rate: number of patients who delivered a live birth divided by the number of patients who had clinical pregnancy × 100.
Multiple pregnancy rates: number of patients who delivered more than one live birth divided by the number of patients who had clinical pregnancy × 100.
p determined by Chi-squared test.
