Review in Drugs, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07046429 (Effect of Supplemental Nightly Melatonin On REM and Cognition in Hepatic Encephalopathy), which is not on this map. Cited by 151 papers, 6 of them syntheses that pooled it.

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.

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.

Abstract

In general, hepatic encephalopathy (HE) is defined as a brain dysfunction caused by liver insufficiency and/or portal-systemic blood shunting. This article relates to the so-called type C HE: that is, HE in patients with liver cirrhosis. It manifests as a wide spectrum of neurological or psychiatric abnormalities, ranging from subclinical alterations, detectable only by neuropsychological or neurophysiological assessment, to coma. Several scales have been developed for grading the extent of HE. The most often used is the West Haven criteria (WHC), which differentiate between four grades of clinically overt HE. Patients with liver cirrhosis without clinically overt symptoms of HE but neuropsychological or neurophysiological findings indicating brain dysfunction are considered to have minimal hepatic encephalopathy (MHE). For simplification, some experts suggest differentiating between covert HE (MHE plus grade I HE according to WHC) and overt HE (WHC grades II-IV). Diagnosis of both MHE and overt HE is hampered by the fact that none of the symptoms of HE or the findings in the various diagnostic measures applied are specific. Thus, a diagnosis of HE or MHE can only be made after exclusion of other possible causes of brain dysfunction.
