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

Quaternary ammonium analogues of atropine that are unable to cross the blood-brain barrier are used to alleviate peripheral muscarinic toxicity in animal models of epilepsy produced by systemic administration of pilocarpine or diisopropylfluorophosphate (DFP). Currently, methylatropine is the most popular and potent of these quaternary derivatives; however, it is expensive and produced in limited quantity. Here, we propose the use of ethylatropine bromide as an alternative to methylatropine. The synthesis of ethylatropine bromide is simple, inexpensive and has low environmental impact. We demonstrate the efficacy of ethylatropine bromide to antagonize the carbachol induced rise in intracellular calcium in a calcium mobilization assay, and its ability to prevent pilocarpine-induced total fluid secretions in mice without blocking pilocarpine-induced seizures. The ease of synthesis, cost effectiveness, and efficacy makes ethylatropine bromide a desirable alternative to methylatropine as a peripherally restricted acetylcholine receptor antagonist.
