A Surprising Cause of Vitreous Base Avulsion: Presence of an Intraocular Pen Tip.

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
To present the outcomes in a patient who underwent acute vitreous base avulsion as a result of a penetrating ocular trauma with a pen and the intraocular retention of the pen tip. A 13-year-old female patient presented with a penetrating ocular injury with a pen. Upon ophthalmological examination, visual acuity was found to be 20/20 in the right eye, and counting fingers from 3 m in the left eye. Scleral penetration was observed 5 mm temporal from the limbus in the superotemporal region of the left eye. Acute vitreous base detachment was apparent with the slit lamp examination, which became visible as a vertical line in the temporal quadrant. The detachment was imaged with anterior segment and ultra-widefield fundus photography. An intraocular foreign body consisting of the tip of the pen was detected. Although vitreous base avulsion is a common outcome of blunt ocular trauma, it is reported less frequently due to difficulties in its detection. To the best of our knowledge, this is the first case reporting vitreous base avulsion due to an intraocular pen tip, which was treated successfully.
