Table 1. The baseline characteristics of the patients and samples in the study.

Number of samples (without RRT)	1,013
Number of patients (without RRT)	445
Patient sex	Men: 254/445 (57.1%)
	Women: 191/445 (42.9%)
Patient age (median, years)	57
Range (years)	22–76
Median enzymatic creatinine µmol/L (mg/dl)	76 (0.86)
Range µmol/L (mg/dl)	20–434 (0.23–4.91)
Median Jaffé creatinine µmol/L (mg/dl)	80 (0.90)
Range µmol/L (mg/dl)	28–431 (0.32–4.87)
Median bilirubin µmol/L (mg/dl)	26 (1.52)
Range µmol/L (mg/dl)	2.2–1096.8 (0.13–64.14)
Median INR	1.3
Range	0.8–9.0
Median MELD-E score	11
Range	6–40
Median MELD-J score	11
Range	6–40
Number of samples with MELD scores (MELD-E)
6–10 points	442
11–20 points	419
21–30 points	124
31–40 points	28
Number of samples with a maximum MELD score >40 (enzymatic and Jaffé creatinine measurement methods)*	4

*According to the applicable regulations [9] MELD scores were limited to 40 and rounded to an integer before being reported to the transplantation organization. The samples had MELD scores >40 independently from the method that was used for creatinine measurement.
