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

Acute hyperammonaemia (HA) causes cerebral oedema and severe brain damage in patients with urea cycle disorders (UCDs) or acute liver failure (ALF). Chronic HA is associated with developmental delay and intellectual disability in patients with UCDs and with neuropsychiatric symptoms in patients with chronic liver failure. Treatment often cannot prevent severe brain injury and neurological sequelae. The causes of the brain oedema in hyperammonaemic encephalopathy (HAE) have been subject of intense controversy among physicians and scientists working in this field. Currently favoured hypotheses are astrocyte swelling due to increased intracellular glutamine content and neuronal cell death due to excitotoxicity caused by elevated extracellular glutamate levels. While many researchers focus on these mechanisms of cytotoxicity, others emphasize vascular causes of brain oedema. New data gleaned from expression profiling of astrocytes acutely isolated from hyperammonaemic mouse brains point to disturbed water and potassium homeostasis as regulated by astrocytes at the brain microvasculature and in the perisynaptic space as a potential mechanism of brain oedema development in hyperammonaemia.
