Abbreviations: BP, blood pressure; eGFR, estimated glomerular filtration rate. Data are number (%), mean ± SD, or median (inter-quartile range).
aThese subjects were excluded due to the single measurement of blood pressure.
bExcludes subjects taking glucose-lowering drugs (n = 17,147 and 181,036).
cExcludes subjects taking lipid-lowering drugs (n = 15,861 and 165,953).
dIncludes subjects with data for eGFR (n = 13,374 and 106,506).
