Treatment of chronic oroantral fistula with platelet-rich fibrin clot and collagen membrane: a case report.
Article in Clinical, cosmetic and investigational dentistry, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 2 of them syntheses that pooled 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.
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
An oroantral fistula is a complication of the maxillary posterior teeth that can occur after a tooth extraction that affects the maxillary sinus. Improper management may lead to a persistent fistula, which may become chronic. In this case report, platelet-rich fibrin (PRF) was used with a collagen membrane to close a chronic fistula in a single patient. A flap was raised, the oroantral fistula tract was eliminated, and the opening was closed with a resorbable membrane as a first layer and covered with a PRF clot as a second layer. The flap was closed, and the patient was followed up for suture removal and confirmation of complete soft tissue closure. The postsurgical sign and symptoms of the patient disappeared in the first week; complete tissue healing was detected within 2 weeks, and tissue hypertrophy was observed in the fourth week. The use of PRF may have advantages for soft-tissue healing and for accelerating soft tissue formation by subsequent hypertrophy.
