Relationship between ECV and histological evidence of interstitial fibrosis on biopsy (CVFmean) for a all biopsies, and b biopsies containing only myocardium. The trendlines are based on regression models, with ECV as the independent variable, and Log₂CVFmean as the independent variable. This relationship was not found to be statistically significant when all biopsies were included within analyses (a, Rho = 0.18, P = 0.101, N = 83), but became statistically significant when limiting analyses to biopsies that contained only myocardium (b, Rho = 0.33, P = 0.015, N = 56)
