Figure 1 Association of cystatin-C levels with mortality in elderly persons with heart failure, stratified by creatinine (Cr) and estimated glomerular filtration rate (eGFR) levels. The figure displays the annual mortality risk for participants with cystatin-C levels above (high) or below (low) the median of 1.26 mg/l. The adjusted hazard ratios (HR) compare high versus low cystatin-C levels among subgroups of participants with high creatinine (above median value of 1.05 mg/dl) or low creatinine (<1.05 mg/dl), as well as by high eGFR (>61 ml/min/1.73 m2) or low eGFR (<61 ml/min/1.73 m2).
