  • The Renal Iohexol-Clearance Survey Follow-Up Study. The estimates represent the interaction between time and 1 SD higher TNFR2 and 1 mg/L higher hsCRP on the annual change in mGFR/eGFR. A positive estimate represents a slower decline. Each row represents a separate linear mixed model with the different mGFR/eGFR as dependent variable. TNFR2, soluble TNF receptor 2; hsCRP, high-sensitivity C-reactive protein; mGFR, measured GFR; 95% CI, 95% confidence interval; eGFRcre, eGFR on the basis of creatinine; eGFRcys, eGFR on the basis of cystatin C; eGFRcrecys, eGFR on the basis of creatinine and cystatin C.
