Bland-Altman plots to compare the diffusion metrics obtained by each centre independently. Caption: Based on a paired t-test, the diastolic FA is highly statistically significantly different (p < 0.001, difference Δ = 0.04), while systolic ADC (Δ = 0.05 × 10-3 mm2/s), FA (Δ = 0.01) and diastolic ADC (Δ = 0.06 × 10-3 mm2/s) are not found to be statistically different.
