A Normalised radius against Strahler order for our data and for previously published rat kidney vascular data derived from Nordsletten et al.11. B The data are plotted for log(Radius), showing a similar pattern but with a significant statistical difference is found between the best fit for the two datasets. Ci Plot of Parent vessel cubed against Sum of cubed child vessels, Murray’s Law is shown in orange hatched line, points from each Truncated Strahler order are differentiated for clarity. Cii Plot of the log of the number of terminal downstream network ends against the radius for all segments in the network. The purple line shows the fit from the Standard Major axis regression, with the intercept a which is the radial scaling exponent and the 95% confidence intervals shown on the plot.
