Table 2 Positive likelihood ratios and pretest and positive post-test odds for mortality given a positive EVLW test

From: Is extravascular lung water index useful for the diagnostic accuracy of lung injury in patients with shock? We need more evidence

  1. The positive extravascular lung water (EVLW) test is defined as EVLW/ABW of greater than 10 mL/kg, EVLW/PBW of greater than 10 mL/kg, and EVLW/PBV of greater than 1.5. ABW, actual body weight; ALI, acute lung injury; ARDS, acute respiratory distress syndrome; CI, confidence interval; LHR, likelihood ratio; PBV, pulmonary blood volume; PBW, predicted body weight; sLI, severe lung injury.
