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

backgroundPrevious clinical trials of α7-nicotinic acetylcholine receptor agonists (α7-nAChR agonists) showed mixed results in treating the cognitive and negative symptoms of schizophrenia.

aimsTo assess the efficacy and safety of α7-nAChR agonists in treating the cognitive and negative symptoms in schizophrenia.

methodsA literature search was conducted to identify randomized double-blind placebo-controlled trials for schizophrenia published before May 26, 2017, by searching PubMed, Embase, ClinicalTrials.gov, the Cochrane Library and the Chinese language databases CNKI, Wanfang, and VIP Data. The effects of α7-nAChR agonists were evaluated for overall cognitive function and negative symptoms by calculating standard mean difference (SMDs) between active drugs and placebo added to antipsychotics.

results8 studies with low bias were included. We found no statistically significant effects of α7 nAChR agonists on the overall cognitive function (SMD=-0.10[-0.46, 0.25],

conclusionα7-nAChR agonists may not be effective in reversing overall cognitive impairments and negative symptoms in patients with schizophrenia as adjunctive therapies.
