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) is a type of calcium pyrophosphate deposition disease that causes inflammation and pain due to calcium deposition in the odontoid process. Patients typically present with acute cervical pain often associated with fevers, elevated ESR and CRP, and leukocytosis. This presentation has a broad differential and raises concern for diagnoses such as giant cell arteritis and meningitis. In this case report, we describe a patient with classic CT scan findings of odontoid calcifications diagnosed with treatment-refractory CDS.
