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
backgroundThere is no high level of evidence for the treatment of fistulous empyema. We report here a promising technique for closure of a bronchopleural fistula using costal cartilage as a bronchial embolus. CASE PRESENTATION: The patient is a 79-year-old man. A computed tomography scan diagnosed a fistulous empyema associated with perforation of lung abscess of right middle lobe. After thoracoscopic curettage of the right empyema cavity, right middle lung resection and intercostal muscle flap coverage over the bronchial stump were performed. Seven months after the surgery, a bronchopleural fistula developed. Bronchoscopy revealed fistulas in the middle lobe bronchus and B3b. After the open window thoracostomy, the empyema cavity was cleaned up. The empyema cavity remained from the anterior to the lateral thoracic region of the second to fourth ribs. A part of the second through fourth ribs that formed the ceiling of the pleural empyema cavity was removed to create space for skin and thickened parietal pleura to fill the cavity. The costal cartilage obtained from the rib resection was trimmed and harvested to fit into the diameter of the bronchopleural fistula. The free costal cartilage was sutured and fixed with five stitches with 3-0 PDS. The visceral pleura was covered with the thickened parietal pleura and skin and fixed airtight. To maintain a tight seal, a Blake® silicone drain was inserted between the visceral pleura and the thickened parietal pleura, and a suction reservoir was utilized to sustain negative pressure. The drain was removed on the 21st day. As of 21 months postoperatively, the skin and thickened parietal pleura flap has maintained its integrity, and there has been no evidence of pus or recurrence of air leaks.
conclusionIn the case of a fistulous empyema extending anteriorly, costal cartilage can be easily harvested, making it a promising option as a lid for fistula closure.
