Aneurysmal subarachnoid haemorrhage-cerebral vasospasm and prophylactic ibuprofen: a randomised controlled pilot trial protocol.
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 3 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
introductionCerebral vasospasm (CVS) is the leading cause of mortality and morbidity following aneurysmal subarachnoid haemorrhage (aSAH). One of the recently implicated underlying mechanisms of CVS is inflammatory cascades. Specific feasibility objectives include determining the ability to recruit 30 participants over 24 months while at least 75% of them comply with at least 75% of the study protocol and being able to follow 85% of them for 3 months after discharge. METHODS AND ANALYSIS: This is a feasibility study for a randomised controlled trial. Eligible participants are adult patients who are 18 years of age and older with an aSAH confirmed by a brain CT scan, and CT angiography, or magnetic resonance angiography, or digital subtraction angiography who admitted to the emergency department within 12 hours of the ictus. Eligible subjects will be randomised 1:1 for the administration of either ibuprofen or a placebo, while both groups will concomitantly be treated by the standard of care for 2 weeks. Care givers, patients, outcome assessors and data analysts will be blinded. This will be the first study to investigate the preventive effects of a short-acting non-steroidal anti-inflammatory drug on CVS and the key expected outcome of this pilot study is the feasibility and safety assessment of the administration of ibuprofen in patients with aSAH. The objectives of the definitive trial would be to assess the effect of ibuprofen relative to placebo on mortality, CVS, delayed cerebral ischaemia, and level of disability at 3-month follow-up. ETHICS AND DISSEMINATION: This study is approved by Mashhad University of Medical Sciences ethical committee (IR.MUMS.MEDICAL.REC.1398.225). Results from the study will be submitted for publication regardless of whether or not there are significant findings. TRIAL REGISTRATION NUMBER: ISRCTN14611625.
