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

rationalePerformance on the Cambridge Neuropsychological Test Automated Battery touchscreen paired-associates learning (PAL) test is predictive of Alzheimer's disease and impaired in schizophrenia and chronic drug users. An automated computer touchscreen PAL task for rats has been previously established. A pharmacologically validated PAL task for mice would be a highly valuable tool, which could be useful for a number of experimental aims including drug discovery.

objectivesThis study sought to investigate the effects of systemic administration of cholinergic agents on task performance in C57Bl/6 mice.

methodsScopolamine hydrobromide (0.02, 0.2, and 2.0 mg/kg), dicyclomine hydrochloride (M(1) receptor antagonist; 2.0, 4.0, and 8.0 mg/kg), and donepezil hydrochloride (cholinesterase inhibitor; 0.03, 0.1, and 0.3 mg/kg) were administered post-acquisition in C57Bl/6 mice performing the PAL task.

resultsScopolamine (0.2 and 2.0 mg/kg) and dicyclomine (at all administered doses) significantly impaired PAL performance. A significant facilitation in PAL was revealed in mice following donepezil administration (0.3 mg/kg).

conclusionsThe present study shows that mice can acquire the rodent PAL task and that the cholinergic system is important for PAL task performance. M(1) receptors in particular are likely implicated in normal performance of PAL. The finding that mouse PAL can detect both impairments and improvements indicates that this task could prove to be a highly valuable tool for a number of experimental aims including drug discovery.
