ECM biomarker levels in relation to fibrosis in a propensity-score matched cohort for graft age. Tukey Boxplots showing differences in biomarker levels between significant fibrosis (≥ F2) and no significant fibrosis (< F2). Each group consisted of 15 patients. Patients were matched using propensity-score matching for time after transplantation in months. Two groups were compared using Mann–Whitney-U test. *indicates p < 0.05; **indicates p < 0.01.
