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

backgroundStroke is a serious public health problem that causes morbidity and mortality throughout the world. Iron chelators are potential neuroprotective drugs to treat patients with both hemorrhagic and ischemic stroke.

objectivesTo evaluate the effectiveness and safety of the administration of iron chelators in patients with acute stroke. SEARCH

methodsWe searched the Cochrane Stroke Group Trials Register (May 2012), the Chinese Stroke Trials Register (May 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 1), MEDLINE (1950 to May 2012), EMBASE (1980 to May 2012), Science Citation Index (1980 to May 2012) and three Chinese databases. In an effort to identify further published, unpublished and ongoing trials we searched ongoing trials registers, checked reference lists, and contacted authors and pharmaceutical companies. SELECTION CRITERIA: We included published and unpublished randomized controlled trials (RCTs) of iron chelator versus no iron chelator or placebo for the treatment of acute stroke. DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results to identify the full texts of potentially relevant studies for inclusion. From the results of the screened searches two review authors independently selected trials meeting the inclusion criteria, with no disagreement. MAIN

resultsWe found no completed RCTs eligible for inclusion in the review. We identified one ongoing RCT but no data were available. AUTHORS'

conclusionsThere is insufficient evidence to support or refute the use of iron chelators for the treatment of acute stroke. Further RCTs are required to assess the effect of iron chelators in people with acute stroke.
