COL18A1 and acute kidney injury: When endostatin was combined with clinical risk factors building the prediction model of p = 1 / (1 + e–z), z = – 4.029 + 0.022 × endostatin + 0.280 × SOFA score – 0.937 × AKI stage 1 + 1.850 × AKI stage 3 for predicting failure to recover, the sensitivity greatly improved to 94.6% (76.8–99.1) and the specificity, PPV and NPV were 72.7% (57.2–85.0), 66.7% (50.3–81.4) and 96.2% (82.3–100.0), respectively.
