Validation Phase II Bland-Altman plots for all two-way comparisons of CD4+ T-lymphocyte counts by FACSCalibur™ and Pima™ point-of-care devices using venous and capillary operated by lay-counselors or laboratory technicians. Note for Fig. 2. The FACSCalibur venous (top row x-axis) is the reference standard. The solid red line is the mean bias and the 95% limits of agreement (LOA) are shown by the dashed red lines. FV, lay-counselor venous blood; FC, lay-counselor capillary blood; LV, laboratory technician venous blood; LC, laboratory technician capillary blood. All units in cells/μl.
