Persistent craniopharyngeal canal with an associated sphenoid sinus fistula.

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
Persistent craniopharyngeal canal (PCC) is a rare congenital anomaly that appears as a linear well-corticated canal running from the sella through the clivus and into the nasopharynx. Case reports of this anomaly have shown it is associated with a range of craniofacial defects, pituitary abnormalities, and meningoencephaloceles. It predisposes patients to bacterial meningitis. In this case a 46-year-old gentleman presenting for preoperative planning for surgical drainage of Potts Puffy tumor was found to have a PCC on CT and MRI. Imaging also demonstrated the presence of chronic inflammation and a fistula extending from the tract into the sphenoid sinus. This unusual presentation of a PCC with a sphenoid sinus fistula broadens the potential clinical presentations of PCC and further emphasizes the ability of this anomaly to serve as a conduit for CNS infection.
