Fig. 5 Control and day 28 oxygen tension profiles. There is a trend toward normalization of oxygen tension levels, although the values remain different at several points along the artery wall. *Values on the x-axis denote statistically different oxygen tension levels.

Fig. 6 Control and day 42 oxygen tension profiles. The oxygen tension profiles are not statistically different at any location through the artery wall.
