Smoothing plots for mean breastfeeding duration with cognitive impairment, stratified by BMI (A(1): <24 km/m2, A(2): ≥24 kg/m2), reproduction period (B(1): <33 years, B(2): ≥33 years), age at first birth (C(1): <21 years, C(2): ≥21 years), respectively. The solid line indicates the point estimation for adjusted odds ratios (ORs) of cognitive impairment, and the dotted lines represent 95% confidence intervals (CIs).
