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
Schwannomas are benign, well-encapsulated, slow-growing nerve sheath tumours composed exclusively of Schwann cells. Ancient schwannomas, a rare variant, are particularly uncommon in the head and neck region, with very few cases reported in the nasal cavity and paranasal sinuses. Here, we describe a case of a 35-year-old male who presented to our otorhinolaryngology department with complaints of right-sided nasal obstruction for the past four years. Imaging demonstrated a lesion with dimensions of 53 × 31 × 46 mm located within the right nasal cavity, involving the middle and inferior turbinate, resulting in expansion of the right osteo-meatal complex, and protruding into the maxillary antrum with thickening of the mucosa. The excision of the lesion was performed using an external approach medial maxillectomy; subsequent histological analysis unveiled the presence of an ancient schwannoma. A comprehensive analysis of existing literature was conducted, focusing on the diagnosis and treatment of this uncommon pathological entity.
