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

backgroundAnesthetic management of non-thoracic surgery in patients with giant bullae is challenging. We present a case of laparoscopic cholecystectomy in a patient with a giant bulla managed with one-lung ventilation (OLV). CASE PRESENTATION: A 75-year-old man with a giant bulla occupying the lower half of the right hemithorax underwent laparoscopic cholecystectomy. We managed anesthesia with OLV to avoid positive pressure ventilation of the giant bulla. Surgery was completed uneventfully; however, postoperative chest radiography indicated a large lucency occupying the entire right hemithorax. Although we suspected a pneumothorax due to a ruptured bulla, chest computed tomography (CT) led to a diagnosis of giant bulla hyperinflation. The giant bulla deflated gradually to its preoperative size within three postoperative days.

conclusionsManaging laparoscopic cholecystectomy in a patient with a giant bulla with OLV resulted in spontaneous hyperinflation of the giant bulla. Chest CT ruled out a pneumothorax.
