methods comparison plot comparing absolute CD4 cells per microliter
of whole blood obtained by the microchip system as compared to
standard four-color flow cytometry processed in parallel on a
FACSCalibur in 61 HIV-infected adult participants. There is a
proportional bias of -50 cells/µl relative to flow cytometry.
Grey line indicates zero bias. Red lines indicate upper and lower
95% limits of agreement.
