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

Amyloid myopathy often occurs in the context of systemic amyloidosis, as a rare manifestation of "light chain" (AL) amyloidosis, accounting for 1% of its incidence. A 58-year-old man with two years history of weakness and edema of lower extremity, elevated creatine kinase (CK), and inflammatory lesions from muscle biopsy which was misdiagnosed as inflammatory myopathy. After immunotherapy, the original symptoms worsened. We later confirmed the disease through MRI, Congo red staining and bone marrow puncture results. Our purpose is that to increase awareness of amyloid myopathy to minimize the risk of misdiagnosis and emphasize the importance of Congo red staining in diagnosing similar conditions.
