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

We report a case of a painful cervical schwannoma arising from the great auricular nerve (GAN) in an 84-year-old man. He presented with a long-standing left cervical mass and progressively worsening severe pain in the infra-auricular and postauricular regions. Physical examination and magnetic resonance imaging revealed a mass along the sternocleidomastoid muscle coursing parallel to the external jugular vein. Based on the characteristic pain distribution and anatomical findings, a schwannoma arising from the GAN was suspected preoperatively. Complete tumor excision with transection of the GAN was performed for pain relief, and histopathological examination confirmed the diagnosis of schwannoma. Postoperatively, the pain resolved completely, with no recurrence during 18 months of follow-up. This case underscores the diagnostic value of characteristic pain distribution and anatomical features in the preoperative identification of a schwannoma arising from the GAN.
