Number of creatinine measurements from study center (SC) and electronic Medical Records (eMR). When combining SC- and eMR-based creatinine values after quality-control, we obtained 2,102,174 creatinine values from 454,907 individuals. We show (A) the distribution of individuals by their number of available creatinine measurements over time (n = 248,844 with = 1 measurement indicated as SC- or eMR-derived in black or red, respectively; n = 206,063 with ≥ 2 measurements over time in gray), (B) the distribution of individuals by the time between 1st and last measurement (“assessment period”), (C) the distribution of the number of measurements by calendar year of assessment, and (D) the distribution of the number of measurements available by age groups (age-at-exam, “exam” referring to the GP-record for eMR or to the examination at the SC visit). For C&D, red colour represents eMR and black colour represents SC data.
