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

backgroundImmune checkpoint inhibitors (ICIs) are monoclonal antibodies that block inhibitory pathways that cancer cells exploit to suppress T-cell activation. Although immune-related adverse events (irAEs) linked to ICI therapy are well documented and encompass dermatologic, endocrine, gastrointestinal, hepatic, and neurologic systems, ICI-related dysautonomia remains a rare phenomenon. Management of ICI-related dysautonomia is undefined. CASE: We report the case of a 57-year-old male patient treated with neoadjuvant nivolumab for Merkel cell carcinoma who developed ICI-related dysautonomia. His dysautonomia was characterized by orthostatic hypotension, urinary retention, hearing loss, and binocular diplopia in addition to the development of ICI-related hepatitis. We describe the patient's course, including the treatment and outcome of his dysautonomia, and review the literature on this rare toxicity.

conclusionDue to the mechanism of action of ICIs, irAEs can present with a wide range of manifestations. In this case, prompt recognition of ICI-induced dysautonomia and timely administration of intravenous immunoglobulin (IVIG) led to significant clinical improvement. ICI-induced dysautonomia is a rare condition that is difficult to diagnose and manage.
