Table 4. Parasite load fold-reduction ratios.

Parasite Load Fold-Reduction†	Polyurethane Group	Gauze-and-Tape Group	t-test p-value*
N	19	17
Superficial dermis (106/g)			.45
Geometric mean	13.2	52.8
Median	11.1	58.8
Range (min, max)	(0, 1,810)	(0, 3,176)
Deep dermis (106/g)			.35
Geometric mean	55.0	76.8
Median	28.3	66.3
Range (min, max)	(2, 4,655)	(8, 1,082)

^†The parasite load fold-reduction ratio is calculated as parasite load at day 1 divided by parasite load at day 10.

*Polyurethane group versus gauze-and-tape group.
