Associations of variables of interest with misclassification rates of cells by CellaVision™ DM96 analyser, Chris Hani Baragwanath Academic Hospital haematology laboratory, Johannesburg, South Africa, 2012–2013 (N = 149).^†

Variable of interest	Adjusted β co-efficient	Standard error	p-value
HIV infection	2.7	2.0	0.17
Evidence of infection	0.72	2.2	0.73
Malignant cells present	8.0	4.0	0.049
History of malignancy	-2.8	3.7	0.45
History of chemotherapy	2.1	3.6	0.56
White cell count	0.06	0.03	0.035

r² = 0.17; (P < 0.0001)

^†Multivariate linear regression analysis was performed to assess the relative impact of variables of interest on misclassification rates. Any data point with a standard residual of greater than 2.5 was excluded from analysis and p-values less than 0.05 were considered statistically significant.
