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

Cerebral edema (CE) is a major component of early brain injury from aneurysmal subarachnoid hemorrhage (SAH). Despite the utility of blood-based protein markers, biomarkers targeting cerebral edema have yet to be developed. We performed a targeted proteomic search analyzing 141 proteins in plasma samples taken from 80 adult patients within 48 hours after aneurysmal rupture to identify plasma biomarkers of cerebral edema. The protein expression profiles were analyzed for associations with a higher level of the subarachnoid hemorrhage early brain edema score measured in admission computed tomography scans. Five differentially expressed proteins-brorin, ectodysplasin A2 receptor, layilin, scavenger receptor class A member 5, and activin A receptor like type 1 (ACVRL1)-were identified. To confirm our findings, in a separate cohort of 75 adult patients with SAH, these biomarker candidates was analyzed using a different confirmatory analytic method-enzyme-linked immunosorbent assay-based on the plasma samples collected within 48 hours after aneurysmal rupture. ACVRL1 levels consistently showed a decrease expression levels as the severity of edema increased. The association between CE and ACVRL1 was significant before and after adjusting for patient factors.
