Adult age and gender adjusted associations of milk intake (breastfed vs. formula/cows' milk fed or by quartile of formula/cows' milk consumed) at 10 days, 6 weeks and 3 months during infancy with fasting glucose, fasting insulin, insulin sensitivity (ISI₀) and insulin secretion (CIR₃₀) measures in later life in subjects included in the final analysis (mean and (95% CI)).

<p><i>P</i>-values are adjusted for age at follow-up. <i>P</i> for trend was calculated across quartiles of formula/cows' milk intake.</p>1<p>Insulin Sensitivity Index whilst fasting = 10⁴/(I₀×G₀).</p>2<p>Corrected Insulin Response at 30 minutes = 100×I₃₀/(G₃₀×(G₃₀−70).</p>†<p>Geometric means with 95% CI.
