Baseline characteristics of the study population, categorized by glomerular filtration rate (eGFR) and coronary flow reserve (CFR).

CKD-EPI = Chronic Kidney Disease Epidemiology Collaboration equation, eGFR = estimated glomerular filtration rate, HRT = hormone replacement therapy, SBP = systolic blood pressure, DBP = diastolic blood pressure, HTN = hypertension, CAD = coronary artery disease, DASI = Duke Activity Status Index, HDL = high density lipoprotein, LDL = low density lipoprotein, Hs-CRP = high-sensitivity C-reactive protein, Q1 = 25th percentile, Q3 = 75th percentile, IL-6 = interleukin 6, SAA = serum amyloid A. P-values represent the comparison between four GFR/CFR combination groups. P-values for all variables except age were adjusted for age.Baseline characteristics of the study population, categorized by glomerular filtration rate (eGFR) and coronary flow reserve (CFR).
