Spearman’s correlation coefficients (top) and p values (bottom) are reported.
CRP, C reactive protein; DBP, diastolic blood pressure; DHS, Dallas Heart Study; DHS-1, DHS phase 1 (2000–2002); ΔeGFR, eGFR at DHS-2 minus eGFR at DHS-1; eGFR, estimated glomerular filtration rate; SBP, systolic blood pressure; SGlu, serum glucose; SMg, serum magnesium.
