Among term infants, with or without sepsis, the strongest positive correlation was between carnitine and acetylcarnitine (ρ = 0.8, Supplementary Figs S1 and S2), while the strongest negative correlation was between methylmalonylcarnitine and relative fetal-to-adult Hb level (ρ = −0.3, Supplementary Figs S1 and S2). Here, GSTM1 is linked to Sepsis.
