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

noneNarcolepsy type 1 is characterized by excessive daytime sleepiness and cataplexy, as well as hypocretin deficiency. Cataplexy (the loss of voluntary postural muscle tone, often in response to emotional stimuli) is one of the most disabling features and is associated with significant social impairment and risk of injury. Cataplexy is usually alleviated by antidepressants sodium oxybate and pitolisant. In this case report, we describe three patients with severe, drug-resistant cataplexy who experienced a dramatic improvement when treated with tropatepine, an anticholinergic muscarinic antagonist (commonly used to prevent neuroleptic-induced parkinsonism) after the usual treatments had failed. The single side effect was mild mouth dryness. In addition to providing a new therapeutic option for resistant cataplexy, this benefit supports a role of cholinergic muscarinic transmission in rapid eye movement sleep atonia.
