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

Crowned dens syndrome (CDS) typically manifests as acute neck pain accompanied by calcifications around the odontoid process. However, such findings may obscure more serious underlying pathologies. We report a case of an 85-year-old man on edoxaban who presented with acute neck pain and atlantoaxial calcifications on computed tomography (CT), initially suggestive of CDS. Subsequent mild neurological deficits prompted cervical magnetic resonance imaging (MRI), which revealed a spontaneous cervical epidural hematoma (SCEH) extending from C2 to C4. The patient was managed conservatively and achieved complete recovery. This case highlights the importance of considering SCEH in the differential diagnosis of severe neck pain, even when odontoid calcification is observed on CT, especially in patients receiving anticoagulant therapy. Thorough clinical evaluation and close follow-up are essential for timely diagnosis and management.
