Two-Staged Bronchoscopic Lung Volume Reduction: A Single US Academic Center Retrospective Analysis Demonstrating Reduction in Pneumothorax.

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
Staged Bronchoscopic lung volume reduction (BLVR) has been proposed to reduce the risk of pneumothorax in patients with emphysema, though evidence to date is limited. We present a retrospective series from a single US academic centre, evaluating pneumothorax and other complications following staged BLVR. Seventeen patients underwent staged BLVR at our centre. Two illustrative cases are presented: (1) a case of pneumothorax post-staged BLVR managed conservatively without chest tube insertion, and (2) a patient who initially developed pneumothorax after single-stage BLVR, subsequently completing staged BLVR without complications. Overall, the pneumothorax rate within 45 days was 11.8%, and none of the events required tube drainage or valve removal. This retrospective analysis suggests that staged BLVR may reduce the incidence of pneumothorax. Larger, randomised controlled trials are warranted to confirm these potential benefits.
