As we did not expect a positive association of breast-feeding with the “inflammation” and “dyslipidemia/high leptin” biomarker status, we conducted sensitivity analyses (see S1 File) using (1) exclusive breast-feeding as well as (2) a binary indicator for ‘at least 6 months exclusive breast feeding’ (vs ‘less than 6 months’) instead of total breast-feeding duration (including breast-feeding combinations e.g. with formula milk). The gene discussed is LEP; the disease is metabolic syndrome.
