Analysis of mean MN frequencies versus MN frequencies of lymphocytes and MN frequencies of buccal cells

						Confidence interval
		Mean	SD	DM	SD of difference	Lower	Upper	*p-value*
Control	Lymphocytes (N = 27)	1.11	1.28	−8.59	0.89	−10.43	−6.75	<0.001
Control	Buccal cells (N = 27)	9.70	4.76	−8.59	0.89	−10.43	−6.75	<0.001
Cutters	Lymphocytes (N = 16)	8.87	4.05	−13.87	1.78	−17.68	−10.07	<0.001
Cutters	Buccal cells (N = 16)	22.75	5.78	−13.87	1.78	−17.68	−10.07	<0.001

N number of subjects per group considered in the analysis, SD Standard Deviation, DM Differences of the mean, considered statistically significant when p < 0.05. We only considered both individuals for which the obtained information was collected in these analyses.
