Association between Urine and Plasma IL-6 and Parameters of Cardiorenal Syndrome.
Whiskers represent 95% CI. Analyses of urine IL-6 were adjusted for plasma IL-6; analyses of plasma IL-6 were adjusted for urine IL-6. IL=interleukin. SD=standard deviation. eGFR=estimated glomerular filtration rate. *adjusted for use of ACEI/ARB. **adjusted for baseline characteristics including age, race, NT-proBNP, use of ACE-I/ARB, home loop diuretic dose, and eGFR. Urine IL-6 levels indexed to urinary creatinine. Due to the skewed distribution of urine and plasma IL-6 variables, a log transform was applied before performing logistic and Cox regressions.
