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

Table 2 Pearson's correlation coefficients for creatinine values measured using the laboratory reference (venous serum creatinine) and StatSensor™ creatinine, subdivided by study centre, renal function and gender
