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

rationaleThe use of intravenous valproate is not approved for clinical practice in psychiatry. Literature data pointed out for a potential usefulness of this route of administration for valproate, but there is no actual consensus.

objectivesThe aim of the present systematic review is to assess the effectiveness of intravenous valproate in agitation as well as general safety.

methodsA systematic review of studies evaluating the use of intravenous valproate in agitation was conducted. Additionally, safety was evaluated in all randomized trials involving the use of intravenous valproate in all medical conditions (epilepsy, migraine and psychiatric conditions).

resultsFor the systematic review on effectiveness in agitation, the search yielded 965 articles overall. After removing duplicates, 9411 articles were screened by title and abstract, and 39 of these were evaluated at a full-text level. Six studies were considered eligible for qualitative synthesis: one RCT and case report (n = 3), followed by cohort studies (n = 2). For the systematic review on safety, twenty-two RCTs were considered eligible for quantitative synthesis.

conclusionIntravenous valproate seems efficacious in reducing agitation in psychiatric patients; it generally appears safe compared to other neuroleptics or antiepileptics. However, the evidence is still not strong as it  relies mainly on open-label studies or case series.
