The mean cellularity was negatively correlated with both the ADCmin and the ADCmean and could be fitted to either of these with a simple linear regression model which was highly significant (for ADCmin, F = 7.99, p = 0.013 and for ADCmean F = 5.56, p = 0.033).
This effect was also seen when the median ADCmin was used as the cutoff to define the two groups but did not reach statistical significance (high ADCmin, progression free survival 18.4 months, 95% CI 13.2 – 23.6 versus low ADCmin, progression free survival 11.3 months, 95% CI 8.4 – 14.3, Log rank = 2.93, p = 0.087).
