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
Murine subarachnoid hemorrhage (SAH) induced using the filament perforation method is a useful in vivo experimental model to investigate the pathophysiological mechanisms in the brain underlying SAH. However, identifying mice with comorbid acute neurogenic pulmonary edema (NPE), a life-threatening systemic consequence often induced by SAH, in this model is difficult without histopathological investigations. Herein, we present an imaging procedure involving dual-energy X-ray absorptiometry (DXA) to identify NPE in a murine model of SAH. We quantified the lung lean mass (LM) and compared the relationship between micro-computed tomography (CT) evidence of Hounsfield unit (HU) values and histopathological findings of PE. Of the 85 mice with successful induction of SAH by filament perforation, 16 (19%) had NPE, as verified by postmortem histology. The DXA-LM values correlate well with CT-HU levels (r = 0.63, p < 0.0001). Regarding the relationship between LM and HU in mice with post-SAH NPE, the LM was positively associated with HU values (r
