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

This study aimed to investigate the role of LVV-hemorphin-7 (LVV-H7) in alcohol dependence. LVV-H7 is a short peptide derived from the cleavage of haemoglobin chains that binds to opioid receptors and plays diverse roles in various physiological and pathological processes. Additionally, LVV-H7 is cleaved at higher concentrations in the presence of alcohol. We conducted behavioural experiments in animal models and performed proteomic analyses of CNS tissues from alcohol-addicted rats to identify LVV-H7 binding partners. Using fluorescent microscopy, we confirmed the blood-brain barrier (BBB) permeability of synthesized LVV-H7 and its releasing enzyme inhibitor, pepstatin. Our results revealed a dose-dependent correlation between LVV-H7 quantities and alcohol levels. Mass spectrometry-based analyses identified LVV-H7's protein-binding targets in CNS tissues of addicted rats and the enzymes responsible for their degradation. These findings highlight the significant role of LVV-H7 in the mechanisms underlying alcohol dependence and indicate the potential role of hemorphin as a therapeutic target.
