Table 4. Microorganisms growth in thioglycolate broth and glucose broth and comparison between group I and group II by Chi-square test.

	n (%)
Thioglycolate broth (+)a	Pre dressing (n = 100)	Postoperative day 6 (n = 94 / n = 92)
Group I	26 (26.0)	39 (41.5)
Group II	27 (27.0)	21 (22.8)
Group I vs. Group II (Chi-square test)	p = 0.873	p = 0.006
Glucose broth (+)a
Group I	28 (28.0)	44 (46.8)
Group II	30 (30.0)	24 (26.1)
Group I vs. Group II (Chi-square test)	p = 0.755	p = 0.003
