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

purposeSerious immune checkpoint inhibitor (ICI)-related neurotoxicity is rare. There is limited data on the specifics of care and outcomes of patients with severe neurological immune related adverse events (NirAEs) admitted to the Intensive Care Unit (ICU). MATERIALS AND

methodsRetrospective study of patients with severe NirAEs admitted to the ICU at 3 academic centers between January 2016 and December 2018. Clinical data collected included ICI exposure, type of NirAE (central [CNS] or peripheral nervous system [PNS) disorders), and patient outcomes including neurological recovery and mortality.

resultsSeventeen patients developed severe NirAEs. Eight patients presented with PNS disorders; 6 with myasthenia gravis (MG), 1 had a combination of MG and polyneuropathy and 1 had Guillain-Barre syndrome. Nine patients had CNS disorders (6 seizures and 5 had concomitant encephalopathy. During ICU admission, 65% of patients required mechanical ventilation, 35% vasopressors, and 18% renal replacement therapy. The median ICU and hospital length of stay were 7 (2-36) and 18 (4-80) days, respectively. Hospital mortality was 29%. At hospital discharge, 18% of patients made a full neurologic recovery, 41% partial recovery, and 12% did not recover.

conclusionSevere NirAEs while uncommon, can be serious or even life-threatening if not diagnosed and treated early.
