1 · What the graph read from it

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.

2 · The registry

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

Empyema with bronchopleural fistula (BPF), defined by persistent air leak with pleural infection, undermines negative-pressure drainage and often leads to highly invasive procedures such as fenestration. While endobronchial Watanabe spigots (EWSs) have mainly been used for postoperative or chronic fistulas, their role as an early intervention in acute infectious empyema with BPF remains uncertain. We report three consecutive frail patients with acute empyema and persistent air leak due to BPF treated using a prospectively predefined early EWS approach. After adequate drainage and antibiotics failed to seal the fistula, endobronchial occlusion was performed at the earliest bronchoscopic opportunity before considering fenestration. In all cases, EWS placement achieved complete cessation of air leak, allowed chest tube removal within 6-26 days and obviated fenestration. Diverse microbiology, including polymicrobial infection and nontuberculous mycobacteria, was controlled without observed device-related infection or migration. Early EWS may offer a minimally invasive, fenestration-sparing option in selected patients.
