Descriptive of combined data from electronic Medical Records (eMR)- and study center (SC)-based eGFR. The dataset for eGFR from SC and eMR combined comprised 454,907 individuals with ≥ 1 eGFR assessment and overall 2,102,174 assessments of eGFR derived from bias-corrected creatinine. (A) Shown are age-group-specific eGFR distributions14 based on data from SC (black) and eMR (bias-corrected, green). This was limited to the 1st eGFR assessment from SC or eMR, respectively. We also show eGFR distributions at (B) first and (C) last assessment (omitting 48 extreme values ≥ 150mL/min/1.73m2).
