Forest plot of the sensitivity, specificity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR) of urinary TIMP-2 and IGFBP7 at a cut-off of 2.0 (ng/mL)2/1000 for the diagnosis of acute kidney injury. (A) sensitivity, (B) specificity, (C) PLR and (D) NLR. IGFBP7 = insulin-like growth factor binding protein 7, NLR = negative likelihood ratio, PLR = positive likelihood ratio, TIMP-2 = tissue inhibitor of metalloproteinase 2.
