We will similarly summarise the data separately for the derivation and validation samples and for the original and our modified RCRI. Original RCRI is based on Lee et al.3
CAD, coronary artery disease; CHF, congestive heart failure; CKD-Epi, Chronic Kidney Disease Epidemiology Collaboration equation; CVE, cerebrovascular events (stroke or transient ischaemic attack); eGFR, estimated glomerular filtration rate; RCRI, Revised Cardiac Risk Index.
