Figure 2 Survival analysis of 9,544 consecutive patients admitted to a CCU and stratified by baseline cCrCl in ml/min per 72 kg. Proportional hazards have been adjusted for age, gender, race, admission diagnosis, history of heart failure, previous aspirin, beta-blocker and angiotensin-converting enzyme inhibitor use, diabetes and baseline hemoglobin in g/dl. This demonstrates an early mortality hazard within five years after discharge for individuals with cCrCl 46.2 ml/min per 72 kg but not on dialysis, as compared with those on dialysis (p < 0.05 for comparisons of groups 3 to 5 versus groups 1 and 2).
