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
Pneumoparotid is a rare cause of parotid swelling characterized by the presence of air in the Stensen's duct and/or the parotid gland. In children, it is often self-inflicted, due to psychiatric disorder or recreational habits (puffing the cheeks, blowing balloons, bruxism…). The diagnosis may be suggested by specific signs such as crepitus or foamy saliva flowing from the Stensen's duct. Here, we present 2 cases of involuntary self-inflicted pneumoparotid, diagnosed by ultrasound and CT, in a child and a teenager. Imaging is useful for diagnosis and excluding complications. Ultrasonography may be sufficient to make the diagnosis of pneumoparotid but is less sensitive than CT. CT can make the diagnosis, but also more completely explores the deep cervical spaces and the thorax, especially important in cases with respiratory symptoms. Treatment is usually conservative, in association with behavioral counselling or psychologic/psychiatric therapy, to avoid activities leading to intra oral pressure increase.
