Correlation between %Hb loss and anti-EPO antibody (all mice combined). Total number of samples n = 23 (Balb/c (8), B6 (5), CBA (6), NZW (4)). Dotted lines are 95% confidence intervals and the continuous line is the line of best fit. r is Pearson coefficient. Blood was harvested at minimum Hb in the course of monitoring the haematological and parasitological parameters. These are values of two separate experiments.
