Electrical impedance tomography can rapidly detect small pneumothoraces in surfactant-depleted piglets.
Article in Intensive care medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
purposeDiagnosis of pneumothorax relies on clinical suspicion and chest X-ray, and is often delayed. We aimed to determine whether electrical impedance tomography (EIT) can accurately identify the presence of surgically created pneumothoraces before significant changes in clinical parameters.
methodsSix anesthetized and muscle-relaxed piglets with surfactant-depleted lungs were studied. Following chest drain insertion into the right ventral chest, 10-20 ml aliquots of air were instilled into the pleural space to a maximum volume of 200 ml. The pneumothorax was drained by attaching a Heimlich valve to the chest drain. At each instillation and after draining the pneumothorax, global and regional end-expiratory intra-thoracic volumes (EEV) were measured using respiratory inductive plethysmography (RIP) and EIT concurrently with [Formula: see text], heart rate and blood pressure.
resultsA significantly greater change in both global EEV(RIP) and EEV within the right ventral quadrant was seen at all volume instillations, from as little as 10 ml, compared with all other quadrants. There was no difference in EEV within the left ventral and both dorsal quadrants. Sp(O)(2) fell below 90% at 100 ml instillation. Tachycardia occurred at 140 ml instillation. EIT identified a 60% resolution of pneumothoraces within 60 s of attachment of the Heimlich valve.
conclusionsEIT accurately detects very small pneumothoraces before physiological parameters change.
