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

In rice (Oryza sativa), defects in endosperm development can give grains a chalky texture, which decreases grain quality and is thus undesirable for breeding and marketing. However, the molecular basis of chalkiness remains largely unknown. Here, we identified CHALK10, which encodes an F-box protein that negatively regulates rice chalkiness. The chalk10 mutant exhibited abnormal starch granule development, decreased starch content, and altered starch physicochemical properties compared with the wild type. CHALK10 interacts with the gibberellin (GA) oxidase SEMIDWARF-1 (SD1) and promotes the ubiquitination and degradation of SD1 through the 26S proteasome pathway. The grains of SD1-overexpressing plants exhibited increased chalkiness; introduction of the sd1 mutant allele into the chalk10 background largely suppressed the enhanced chalkiness observed in the chalk10 mutant. GA levels were higher in the chalk10 mutant than in the wild type, and application of the bioactive GA form GA
