Fig. 1From: Assessment of two POC technologies for CD4 count in MoroccoLinear regression and Bland–Altman analysis for comparison between PIMA, FACSPresto techniques and the reference method. Linear regression (a) and Bland–Altman analysis (b) for absolute CD4 generated by PIMA. Linear regression (c) and Bland–Altman analysis (d) for absolute CD4and % CD4 (e, f) determined by FACSPresto. Linear regression (g) and Bland–Altman analysis (h) for FACSPresto for hemoglobin level. The reference method for CD4 count is the tritest run on FacsCalibur and for hemoglobin is Coulter Ac.T diffBack to article page
