Blinded observers’ cumulative postoperative photographic grading for ecchymosis

	KAOLIN GAUZE SIDE SUPERIOR	STANDARD GAUZE SIDE SUPERIOR	BOTH SIDES EQUALLY EFFECTIVE	ABSENCE OF FINDING ON EITHER SIDE	p-VALUE
Day 1	37	24	70	53	0.171
Day 4	47	19	49	69	0.016
Day 7	53	26	68	37	0.016

P-value is the comparison of “superior side” (kaolin vs. standard gauze) with “sides equally effective” as the second column in the 2x2 table. Cases with no evidence of finding were excluded from analysis.
