Secondary endpoint: agreement between uCrCl and eGFR—scatter plot. Every hollow circle represents a single paired eGFR/uCrCl measurement. Strong variability in uCrCl is observed, with some patients having highly outlying uCrCl measurements. In contrast, the variability of eGFR determinations is much smaller. eGFR estimated glomerular filtration rate, uCrCl urinary creatinine clearance.
