Figure 5From: Development of an erythropoietin prescription simulator to improve abilities for the prescription of erythropoietin stimulating agents: Is it feasible? Haemoglobin variability in simulation B. Hb variability expressed as standard deviation (SD) and delta Hb (absolute value of the difference between consecutive measurements) comparing the 2 administration intervals: monthly M (black columns) and weekly W (white columns). The difference between columns in "Delta Hb" is significant; P < 0.01. N = 25.Back to article page
