Nuclear magnetic resonance spectroscopy metabolite analysis of perfusate during NMP. (A) Orthogonal partial least squares discriminant analysis built on experimental group segregates HOPE and CSS (Q2 = 0.68, P < 0.003). (B) Perfusate succinate levels at early time points. CSS: cold static storage; HOPE: hypothermic oxygenated perfusion; LV: latent variable. n(A) = 25 per group, n(B) = 5 per group.
