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

Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystemic small-vessel vasculitic disease that can present with positive MPO-P-ANCA (myeloperoxidase-perinuclear-anti-neutrophil cytoplasmic antibody). It is a rare condition that is difficult to diagnose. We present the case of a 64-year-old man with late-onset adult asthma and treated nasopharyngeal carcinoma who initially presented to us with proximal myopathy. Thereafter, he developed a constellation of fleeting symptoms which included rhinosinusitis, mononeuritis multiplex, skin vasculitis and arthritis. Blood investigations showed that he had eosinophilia, and skin biopsy demonstrated dermal vasculitis with eosinophils. He was found to be MPO-C-ANCA positive, and although initially thought to have granulomatosis with polyangiitis, the diagnosis was later revised to EGPA. This case highlights the diagnostic challenges with atypical presentations of EGPA and also presents a rare case of positive MPO-C-ANCA that has never been described in EGPA before.
