Protein expressions in perfusate and BALF from transplanted and non-transplanted EVLP donor lungs. Interleaved scatter plots with molecular marker levels expressed in (pg/ml) and lines representing means. *P<0.1. **P<0.05. ***P<0.001. BALF: bronchoalveolar lavage fluid; EVLP: ex vivo lung perfusion; IL: interleukin; TNF-α: tumour necrosis factor alpha; LDH: lactate dehydrogenase; HMGB-1: high-mobility group box-1.
