After adjusting for key confounders including age, BMI, and AMH, no differences were observed between thalassemia and non-thalassemia women in embryo euploidy outcomes (adjusted RR for biopsied blastocysts: 1.06, 95% CI: 0.99–1.13; euploid embryos: 0.96, 95% CI: 0.86–1.08; proportion of euploid embryos: β = −0.03, 95% CI: −0.07–0.01). The gene discussed is AMH; the disease is thalassemia.
