Graph description: Figure 20. Serial measurements of tumour size by CT scan and portal vein blood flow (transit time in sec) for six patients, showing the analysis of covariance model

This is the same scatter diagram as in the previous graph, with six lines added.

The horizontal axis shows tumour size and is numbered 0, 5, 10, 15. The vertical axis shows portal vein transit time in seconds and is numbered 5, 10, 15, 20, 25.

For each subject there is a group of points. For three subjects these form fairly close clusters, for three subjects they appear to show downward trends.

For each subject there is separate line through the points. The lines are all parallel and slope downwards.
