FIG. 4.

Untreated pericardium physical properties. The graph displays the characteristic properties collected from pericardium from three different donors. All data were collected 2 days after harvest. Samples were cut into 1×5 cm rectangles and stored in phosphate-buffered saline until testing. ANOVA statistical tests showed significant difference in the elastic modulus and in the thicknesses (p<0.05), and results from a post hoc Tukey's test are shown on the graphs. Groups that do not share a letter are significantly different.
