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

Subarachnoid hemorrhage (SAH) due to ruptured cerebral aneurysms is the most severe form of stroke, and treatment outcomes remain poor. Brain damage after SAH can be broadly divided into early brain injury (EBI) and delayed cerebral ischemia (DCI). Although the causes of these events are multifactorial, free hemoglobin generated after hemolysis in the subarachnoid space is believed to be one of the most important causative factors. Recently, cerebral lymphatic vessels, previously thought to be non-existent, have been identified, suggesting their involvement not only in maintaining homeostasis but also in brain injury. Furthermore, new findings have been reported regarding cerebrospinal fluid (CSF) circulation. Because intracranial CSF circulation and lymphatic drainage to the extracranial blood and lymphatic vessels affect free hemoglobin metabolism in the CSF, these factors are likely to affect EBI and DCI. In addition, matricellular protein tenascin-C, which we have reported to be involved in the pathogenesis of EBI and DCI, has been reported to inhibit lymphatic vessel proliferation in non-central nervous system pathologies. However, the relationship between post-SAH brain injury and intracranial lymphatics remains unknown. This review aimed to summarize recent findings regarding intracranial lymphatics and CSF circulation and to discuss how they may affect post-SAH pathology.
