Graph description: Figure 12. Histograms of capillary density in two groups of patients

Two histograms, for controls and ulcer patients separately.

Each histogram is uneven and it is difficult to tell the shape, although they might be thought to appear symmetrical.

There are superimposed Normal curves, which fit the data quite well, though it is hard to be sure.
