- In the upper model baseline, MFI abnormality was the independent variable. Model AUC 0.836 [0.747–0.904], Nagelkerke R2 0.359, Hosmer and Lemeshow χ2 4.733, p = 0.822. In the lower model, the presence of abnormal MFI plus tachycardia was the independent variable. Model AUC 0.836 [0.747–0.903], Nagelkerke R2 0.374, Hosmer and Lemeshow χ2 2.670, p = 0.914
- APACHE acute physiologic and chronic health evaluation II, calculated in the first 24 h from ICU admission; ICU Intensive Care Unit; MFI Microvascular Flow Index. Abnormal MFI is defined as MFI < 2.6 for small vessels (diameter < 20 μm). Tachycardia is defined as a heart rate ≥ 90 bpm
