1 · What the graph read from it

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.

2 · The registry

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

Pleomorphic adenoma is a common, benign neoplasm typically located in the major salivary glands. The external auditory canal is an atypical location for a pleomorphic adenoma to originate. Wide surgical excision is essential in cases of pleomorphic adenoma due to its tendency to recur and change into malignancy. We report a case of pleomorphic adenoma emerging in the external auditory canal, which is an atypical location for it to originate. A 23-year-old male presented with swelling and decreased hearing in the left ear for 2 months. On examination, there was a smooth, pink, firm swelling in the cartilaginous part of external auditory canal. Pure tone audiogram and computed tomography of temporal bone were performed. The patient underwent excision biopsy and the diagnosis of pleomorphic adenoma was confirmed after histopathology. Long-term follow-up is recommended as pleomorphic adenoma has the potentiality to recur or transform into malignancy.
