Weaning Outcome is Associated with ELWI and Impaired Diastolic Function.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: To evaluate hemodynamic profiles of critical care patients undergoing spontaneous t-piece trial (SBT) and present weaning failure. Methods: Prospective observational study conducted in ready-to-wean non-cardiac ICU patients. Clinical, echocardiographic and thermodilution-derived variables were recorded before and after a 2-hour SBT. Weaning from mechanical ventilation was defined as preservation of spontaneous breathing for 48 hours following successful SBT. Results: Fourteen patients succeeded weaning, five manifested T-trial-failure and six late-failure. Weaning outcome was significantly associated with ELWI(Extravascular lung-water index), global-end-diastolic index and impaired diastolic function, as indicated by pre-T Doppler early wave velocities (E/Em); Fifty-six percent of participants presented ELWI≥7mL/kg when fulfilling predetermined criteria for weaning. ELWI, impaired pulmonary permeability and left ventricular diastolic dysfunction were independent determinants of ELWI. Conclusions: ELWI before SBT and impaired diastolic function (as indicated by pre-T E/Em) might be weaning outcome determinants and their assessment may allow better risk stratification in weaning decision making.
