Fig. 4From: Serum metabolomic signatures of fatty acid oxidation defects differentiate host-response subphenotypes of acute respiratory distress syndromeAcetylcarnitine and octanoylcarnitine levels positively correlate with inflammatory biomarkers. a Correlation matrix is shown for log (concentration) of biomarkers and relative amounts of carnitine (CAR), acetylcarnitine (ACAR), and octanoylcarnitine (OCT) with log concentrations of serum biomarkers creatinine (Cr), TNFR1, bicarbonate (CO2), RAGE, angiopoietin-2 (ANG2), IL-10, and IL-6 within the cohort. Pairwise correlations are shown for acetylcarnitine and (b) RAGE and (c) TNFR1 with Spearman’s coefficient (ρ) and P values. Pairwise correlations are shown for octanoylcarnitine and log concentrations of (d) RAGE and (e) TNFR1 with Spearman’s coefficient (ρ) and P-valuesBack to article page
