Figure 4
Changes in plasma creatinine concentration relative to the first creatinine measured in the emergency department followed one of three patterns. These patterns are Crincrease (open white circles), in which the increase in plasma creatinine was greater than 20% at 24 hours after cardiac arrest; Crunchanged (closed solid circles), in which plasma creatinine increased no more than 20% or decreased no more than 10% at 24 hours after cardiac arrest, and Crdecrease, in which plasma creatinine decreased exponentially by more than 10% by 24 hours after cardiac arrest.
