Bland-Altman analysis comparing data obtained by flow cytometry and Chipcytometry

Sample/cell population	Bias	95% limits of agreement
All cells and samples	− 1.054	− 17.31	15.20
Cell counts ≥ 5/μl	0.008750	− 7.961	7.978
Cell counts < 5/μl	− 1.585	− 20.87	17.70
T cells	1.315	− 23.62	26.25
B cells	− 0.3833	− 4.463	3.696
Monocytes	− 5.420	− 26.62	15.78
T cell CD4:CD8 ratio	0.2733	− 1.638	2.185

A bias close to zero indicates that both methods generate nearly identical results
