IVF outcome rates (Implantation, Pregnancy, Live Birth) for the entire patient population (ALL) and for the different subsets of the IVF population. The subsets are divided into thin (BMI < 20 kg/m2), normal weight (BMI = 20 to 24.9 kg/m2), overweight (BMI 25 to 29.9 kg/m2), and obese (BMI ≥ 30 kg/m2). Using contingency table analysis and receiver-operator characteristic curves, no significant threshold value was noted for outcome rates throughout the entire data range.
