(A) Distribution of facility IV iron use among Japanese dialysis units in DOPPS I (1999), DOPPS II (2002) and DOPPS III (2006). The percentage of patients within a facility using IV iron was determined for a point-prevalent cross-section of HD patients having ESRD >180 days in each participating DOPPS dialysis unit at the start of each study phase; n = 63 facilities for DOPPS I, n = 60 for DOPPS II and n = 61 for DOPPS III. (B) Distribution of the number of IV iron doses per month given to prevalent HD patients in DOPPS III. Results are based on a point-prevalent cross-section of Japanese HD patients having ESRD >180 days at the start of DOPPS III; analyses were restricted to patients receiving IV iron during the first month after study entry (n = 1336).
