Association between high cystatin C levels and carotid atherosclerosis

Figure 1 Receiver operating characteristic curve for predictive value of serum cystatin C levels. The receiver operating characteristic curve for the predictive value of serum CysC levels in detecting an MCPT of > 2 mm in 128 subjects had an area under the curve of 0.724. A serum CysC level of ≥ 0.73 mg/L indicated an MCPT of > 2 mm with 82.7% sensitivity and 52.6% specificity. CysC: Cystatin C; MCPT: Maximum carotid plaque thickness.
