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

purposeThe azygoesophageal recess (AER) is known as a possible cause of bulla formation in patients with spontaneous pneumothorax. However, there has been little focus on the depth of the AER. We evaluated the relationship between the depth of the AER and pneumothorax development.

methodsWe conducted a retrospective study of 80 spontaneous pneumothorax patients who underwent surgery at our institution. We evaluated the depth of the AER on preoperative computed tomography scans.

resultsRuptured bullae at the AER were found in 12 patients (52.2%) with secondary spontaneous pneumothorax (SSP) and 8 patients (14.0%) with primary spontaneous pneumothorax (PSP) (p < 0.001). In patients with ruptured bullae at the AER, 10 SSP patients (83.3%) had a deep AER while only 2 PSP patients (25%) had a deep AER (p = 0.015).

conclusionsA deep AER was more frequently associated with SSP than with PSP. A deep AER may contributes to bulla formation and rupture in SSP patients.
