4. Fig. 3
Scattergram shows significant decrease in porosity by the finish (F) of stage 2 for both Vasculour-II and Bionit-II grafts (S = start). Not all the columns have 10 plots because of unsatisfactory recordings obtained at the start and finish of a few porosity testings.

5. Fig. 4
Changes in graft porosity with time for the Vasculour-II and Bionit-II grafts in the first three stages of preclotting (I, II, and III). Arrow denotes the mean coagulation time. Each point represents the mean of 10 water porosity measurements on 10 different samples. The curve is ‘sine’ in shape but after full coagulation it follows a negative exponential function of the form: y = ae−bx.
