Evaluating the Risk of Tumors Diseases Based on Measurement of Urinary and Serumal Antioxidants Using the New Agar Diffusion Methods

Table 2

Urine and serum diffusion area (cm²) of tumor patients and healthy people in the two methods.

Diffusion area (cm^2)		Urine			Serum
		Median			Mean ± SD
KMnO4	Tumor patients	1.83	−2.076	0.038	2.02 ± 0.17	−1.424	0.158
	Healthy people	1.54			1.97 ± 0.17
	Tumor patients	1.54	−2.399	0.016	3.20 ± 0.40	−2.867	0.005
	Healthy people	1.13			2.94 ± 0.46

Because urinary diffusion areas in both methods were in nonnormal distribution, nonparametric test was used to compare the results in the two groups. While the serumal diffusion areas in both methods were in normal distribution, -test was used to compare the results in the two groups. SD, standard deviation.
