Microsurgical resection of olfactory groove meningioma via the pterional transsylvian approach with preservation of the bilateral olfactory nerves.

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
Olfactory groove meningiomas are slow-growing tumors arising from the dura of the cribriform plate and adjacent to the crista galli in the anterior cranial fossa. These tumors are frequently diagnosed late and may reach a very large size. Several surgical approaches have been described for olfactory groove meningiomas. The pterional transsylvian approach facilitates preservation of the olfactory nerves in most cases, allows for gross-total resection, and provides early access to vital structures. This video presents the successful treatment of a patient with an olfactory groove meningioma, with preservation of the bilateral olfactory nerves via the pterional transsylvian approach.
