STRUCTURE-FUNCTION ANALYSES OF THE TESTED PRIMARY WOUND DRESSINGS

A, An example of a microscopic image of the Exufiber Ag+ (ExAg-polyvinyl alcohol) dressing. B, Representative microscopy image analysis of the fiber orientation in the Ag-sodium carboxymethyl cellulose (CMC) dressing, showing the normalized planar distribution of fiber orientations in this primary dressing type. C, The strain energy density to failure of the two tested primary dressing types after simulated use of 10 and 15 hours, where the Ag-CMC product has been tested in two configurations, either in full alignment of the principal direction of the fibers of the dressing with the loading axis of the testing machine, or out of such alignment. The error bars are the SDs from the mean values of six test repetitions per test configuration, and an asterisk indicates a statistically significant difference in the relevant outcome measure (P < .01).
