What are the predictors of delayed cerebral ischaemia (DCI) after aneurysmal subarachnoid haemorrhage? An up-to-date systematic review.
Review in Acta neurochirurgica, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeDelayed Cerebral Ischaemia (DCI) remains an important preventable driver of poor outcome in aneurysmal subarachnoid haemorrhage (aSAH). Our ability to predict DCI is based on historical patient cohorts, which use inconsistent definitions for DCI. In 2010, a definition of DCI was agreed upon and published by a group of aSAH experts. The aim of this study was to identify predictors using this agreed definition of DCI.
methodsWe conducted a literature search of Medline (PubMed) to identify articles published since the publication of the 2010 consensus definition. Risk factors and prediction models for DCI were included if they: (1) adjusted for confounding factors or were derived from randomised trials, (2) were derived from prospectively collected data and (3) included adults with aSAH. The strength of studies was assessed based on quality, risk of bias and applicability of studies using PROBAST.
resultsEight studies totalling 4,542 patients were included from 105 relevant articles from 4,982 records. The most common reason for not including studies was failure to use the consensus definition of DCI (75%). No prediction models were identified in the eligible studies. Significant risk factors for DCI included the presence of onsite neuro-interventional services, high Neuropeptide Y, admission leucocytosis, neutrophil:lymphocyte >5.9 and Fisher Grade > 2. All studies had a high or unclear risk of bias.
conclusionsOnly a few studies with high risk of bias have investigated the predictors using consensus-defined DCI. Further studies are warranted to clarify risk factors of DCI in the modern era.
