Autotransfusion in low-resource settings: a scoping review.
Article in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
introductionGlobally, haemorrhage is the leading cause of both maternal mortality and preventable trauma death. For patients suffering from haemorrhage, prompt blood transfusion can be life-saving; however, safe and sufficient blood is often lacking in low-resource settings (LRS). Autotransfusion (AT), in which the patient's own blood is collected and transfused back, is an established alternative to donor blood transfusions, although one that is primarily performed with advanced AT systems. Research on basic AT in LRS is scarce. Therefore, we aimed to consolidate all available information on the current use of basic AT in LRS and to identify AT techniques and devices described for use in such settings.
designScoping review.
methodsWe systematically searched four key databases: PubMed, Web of Science, Global Health and Cochrane Library as well as several grey literature databases and databases of relevant organisations. The final search was conducted on 22 April 2019. We included all types of studies referring to any information on basic AT used or sought to be used in LRS, published in English and dated after 31 December 2008. We synthesised the data from the included studies, results were charted or summarised narratively.
resultsSome 370 records were reviewed, yielding 38 included documents. We found a paucity of scientific evidence as well as contradictory information on the extent of AT use and that AT use is largely undocumented. The most commonly described indications were haemoperitoneum (primarily among obstetric patients) and haemothorax. We identified three AT techniques used in LRS. Additionally, two new devices and one filter are described for potential use in LRS.
conclusionsBasic AT is practiced for certain obstetric and trauma indications. However, context-specific studies are needed to determine the technique's safety and effectiveness. Extent of use is difficult to assess, but our results indicate that basic AT is not a widely established practice in LRS. Future research should address the bottlenecks hampering basic AT availability. New AT devices for use in LRS are described, but their utility and cost-effectiveness remain to be assessed.
