Multivariable adjusted Hb and EPO doses 2004-2010 among patients 0–3, 4–6 and 7–18 months on dialysis. Panel (a) Percentages of patients with Hb < 10 g/dL; Panel (b) Percentages of patients with Hb > 12 g/dL; Panel (c) Weekly EPO doses. Vales are based on white males greater than 65 years old with diabetes as the cause of ESRD. The slopes represent monthly rates of change during each of the three time periods (2004–2006, 2007–2009 and 2010). The “*” indicate that the slope is significantly different from 0. The grey dotted lines are 95% confidence intervals for the adjusted values. The difference in slopes for Hb < 10, Hb >10 g/dL and EPO dose within each ‘time on dialysis’ subgroup between 2004–2006 and 2007–2009 and between 2007–2009 and 2010 were statistically significant except for Hemoglobin < 10 g/dL in the 4–6 month patient subgroup between 2007–2009 and 2010.
