Cl=confidence interval; OR=oddsratio; CAD, Coronary artery disease; CAR,
C-reactive protein to albumin ratio; eGFR, estimated glomerular
filtration rate; IRA, Infarct releated artery
In the ROC analysis performed to predict TIMI flow 0-1, the optimal
predictive value for CAR was 0.375 with 48% sensitivity and 84%
specificity. The ROC curves were compared to evaluate whether CAR has
additional distinctive value on the CRP and albumin levels. CAR’s Area
Under Curve (AUC) value was statistically significantly higher compared
to CRP (AUC: 0.59; 95%CI: 0.55-0.63, p=0.014) and albumin (AUC: 0.57;
95%CI: 0.53-0.62, p=0.028) in predicting TIMI flow 0-1 (Figure 1).
