Accuracy of urinary CCL14 for prediction of persistent AKI. HSROC curve with Prediction and Confidence contours. Circles symbolize estimates of individual primary studies, and a square indicates the summary point of sensitivity and specificity. The HSROC curve is plotted as a curvilinear line passing through the summary point. The overall discriminative accuracy of the urinary CCL14 to predict persistent AKI shows an area under the curve (AUC) of 0.84 (0.80–0.87). AKI, acute kidney injury; CCL14, C–C motif chemokine ligand 14; HSROC, hierarchical summary receiver operating characteristic
