eGFR is more strongly associated with adverse outcomes when cystatin C is included
1. In this cohort study, estimated glomerular filtration rate based on both creatinine and cystatin C (eGFRcr-cys ) was more strongly associated with cardiovascular events than estimates based on creatinine alone (eGFRcr). 2. Nearly one-third of individuals were reclassified into a different severity category after recalculation. Evidence Rating Level: 2 (Good) Study Rundown: GFR is used
