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
In Wilson disease (WD), excess copper provokes hepatocyte death due to impaired copper excretion, ultimately causing either acute or chronic liver damage. Current therapeutic compounds fail to reduce hepatic copper near to physiological levels, leaving lifelong, several times daily treatment as the only choice for patients. We have previously shown that a bacteria-derived methanobactin, termed ARBM-101, most efficiently depleted excess liver copper in still healthy WD rats. Here we report, for the first time, that mechanistically this is due to endosomal/lysosomal/exosomal trafficking of ARBM-101 in WD hepatocytes, allowing for copper mass excretion via the biliary/fecal route. We further show that such liver copper excretion occurs within minutes in vivo to detect copper-bound ARBM-101 in feces. This efficacy allows for specialized treatment regimen to rescue acute liver failure in WD rats. Moreover, also shown for the first time, it avoids fibrosis development in WD mice. Thus, judging from the results in two rodent species and human hepatocytes, this study advocates the development of ARBM-101 for WD therapy.
