Table 2 Binary logistic regression analysis for ICU mortality

From: MicroDAIMON study: Microcirculatory DAIly MONitoring in critically ill patients: a prospective observational study

Variables Odds ratio (95% CI) p value
ICU MORTALITY (abnormal MFI)   
APACHE II score 1.204 (1.089–1.331) < 0.001
MFI < 2.6 4.594 (1.340–15.754) 0.015
ICU MORTALITY (abnormal MFI + tachycardia)   
APACHE II score 1.191 (1.077–1.316) 0.001
MFI < 2.6 + tachycardia 10.732 (1.685–68.354) 0.012
  1. 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
  2. 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
