Evaluation of a handheld creatinine measurement device for real-time determination of serum creatinine in radiology departments

Figure 1 Scatter plots, regression equations and correlation coefficients for the correlation for capillary point-of-care serum creatinine vs venous point-of-care serum creatinine for both centres (A), for creatinine values below (B) and above (C) the cut-off-level of 1. 2 mg/dL (venous point-of-care serum creatinine). The Bland-Altman plot for the differences between capillary point-of-care serum creatinine (cSCr) and venous point-of-care serum creatinine (vSCr) for both centres (D).
