Multiple regression analysis of the effect of endogamy and mtDNA on levels of lymphocytes in peripheral blood of calves*

Lymphocyte	R²(%)	Parameter	Coefficient	95% confidence interval	P value
CD8⁺ cells	9.64	Endogamy	0.3065	0.002021 to 0.6110	0.0486
CD8⁺ cells	9.64	mtDNA	0.4988	-3.296 to 4.294	0.7919
CD21⁺ cells	12.56	Endogamy	0.4109	0.03578 to 0.7859	0.0326
CD21⁺ cells	12.56	mtDNA	-0.4894	-5.164 to 4.186	0.8335
γδ^high T cells	21.66	Endogamy	-0.5947	-0.9624 to -0.2271	0.0022
γδ^high T cells	21.66	mtDNA	-3.545	-8.127 to 1.038	0.1259
T/B cell ratio	11.15	Endogamy	-0.09596	-0.1884 to -0.003520	0.0423
T/B cell ratio	11.15	mtDNA	0.06902	-1.083 to 1.221	0.9042

*Significant differences at P < 0.05 are highlighted in italic format. CD4⁺, γδ , γδ^low T lymphocytes and CD4⁺/CD8⁺ cell ratio did not show any significant correlation.
