Novel Respiratory Breath Hold Index: A Predictor for Successful Extubation in Mechanically Ventilated Patients, a Prospective Cohort Study.

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
backgroundLiberation from mechanical ventilation is a major objective in critically ill patients. Various criteria for extubation are used with different success rates. We developed a novel, simple bedside maneuver and index that involves measuring breath-hold duration and forced vital capacity (FVC). We named it the Respiratory Breath Hold Index (RBHI).
methodsWe enrolled 225 mechanically ventilated intensive care unit (ICU) patients who were candidates for extubation. At the end of a spontan eous breathing trial (SBT), and just prior to extubation, patients were asked to hold their breath and perform a stalked FVC maneuver. The ability to perform a breath-hold maneuver and its duration were recorded and compared with a standard SBT.
results171 patients (76%) were successfully extubated, while 54 patients (24%) failed extubation. A successful SBT alone did not predict extubation, as 80.1% of passed SBT and 81.5% of failed SBT patients were extubated successfully (
conclusionHigher RBHI, together with the ability to hold a breath just prior to extubation in mechanically ventilated patients, is more sensitive and specific, and may be superior to standard SBT in predicting a successful extubation.
