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

Vacuolar protein sorting 29 (VPS29) is a pivotal component of the retromer complex, which plays a central role in endosomal trafficking. Numerous studies have investigated its functions in various eukaryotic systems; however, research in plants is still at an early stage. Moreover, the mechanisms controlling its abundance and stability remain largely unknown. In this study, we elucidated the role of constitutive photomorphogenic 1 (COP1) in regulating the abundance of Arabidopsis VPS29 (AtVPS29), a component of the trimeric retromer complex. Degradation of AtVPS29 is delayed by treatment with the proteasome inhibitor MG132, resulting in the accumulation of ubiquitinated AtVPS29 in MG132-treated plants. The AtVPS29 level is higher in
