Weighted linear regression results for the ADC within the lesion [see Figure 3(a) – (c)]. r² is the square of the correlation coefficient, RMSE is the root-mean-square error of the residuals, p is the two-tailed p-value, n is the number of data points. Errors in the intercept and gradient are the 95% confidence intervals.
