Early changes in inflammation-related proteins in the cerebrospinal fluid and plasma of patients with aneurysmal subarachnoid hemorrhage.

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
backgroundAneurysmal subarachnoid hemorrhage (aSAH) is a relatively uncommon but high mortality form of stroke that can result in long-lasting disability. A better understanding of key neuroinflammatory changes during the early phase (<72 h) may provide potential avenues of treatment.
methodsIn an attempt to understand these early changes, we recruited 7 aSAH patients for profiling of longitudinal plasma and cerebrospinal fluid (CSF) proteins at up to 72 h post injury. We additionally compared this to control plasma obtained previously from healthy elderly volunteers. Using the Alamar Biosciences NULISAseq platform, we obtained a comprehensive picture of early peripheral and central inflammatory changes after injury.
resultsThis study demonstrated very early plasma changes across 107 inflammatory proteins, 22 of which showed significant correlations between plasma and CSF. Of these, CXCL12, IL-15, and SAA1 are detectably elevated <24 h in plasma, significantly correlated with CSF levels, and altered as a function of aSAH progression over time during this early phase.
conclusionThis study demonstrates the feasibility of measuring a large number of inflammatory proteins in CSF and plasma from aSAH patients soon after injury. Despite the small sample size and limitations of the control group, we identified several previously reported "hits" that may offer prognostic utility and/or therapeutic potential for aSAH patients: CXCL12, IL-15, and SAA1.
