From: Wear of hip prostheses increases serum IGFBP-1 levels in patients with aseptic loosening
Receiver operating characteristic (ROC) curve generated for the serum IGFBP-1 levels in patients undergoing aseptic hip revision (AL) and primary THA (PR). The area under the curve (AUC) is expressed as mean ± standard error including the 95% confidence intervals (CIs). The dashed diagonal line represents the line of identity or no discrimination. The optimal cut-off value (indicated in the graph) and the associated data for sensitivity and specificity are shown.
