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

Crohn's disease is a chronic inflammatory disease of the digestive tract with extraintestinal manifestations, which include skin conditions, arthritis, ocular inflammation, and several autoimmune conditions. Dermatologic manifestations in Crohn's disease complicate the treatment course and prognosis and should be addressed promptly. Here, we report a 20-year-old male with a history of Crohn's disease, presenting with palpable purpura, consistent with Henoch-Schönlein purpura, upon administration of ustekinumab. The immunoglobulin A vasculitis was treated with prednisone and the discontinuation of ustekinumab. Due to the increased usage of biological agents in inflammatory bowel diseases, associations between biologics and vasculitides should be further studied in Crohn's disease patients for alternative treatment strategies and to understand potential adverse effects caused by biologics in Crohn's disease.
