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

Inositol hexakisphosphate (IP6) is an endogenous organic molecule present in eukaryotes. First characterized as a phosphorus-storage metabolite, it has been subsequently discovered to play a role in modulating a multitude of different biological pathways. Here, we provide a concise overview of the involvement of IP6 in the ubiquitin-proteasome system (UPS). As an allosteric regulator, a molecular glue, and a potential prosthetic group, IP6 directly impacts the activities of multiple major UPS components. We specifically highlight the structural mechanisms through which IP6 binds to individual proteins or multi-protein complexes to control their functions. The serendipitous discovery of IP6 in various protein structures raises questions about the prevalence, identity, and regulation of soluble inositol polyphosphates in the UPS, which have potential translational implications.
