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

Pedicel length is a crucial agronomic trait of cucumbers. Fruit deformation can occur When the pedicel is too long or too short. Moreover, an appropriate pedicel length is advantageous for mechanized harvesting. Therefore, it is essential to investigate the molecular regulatory mechanisms underlying cucumber pedicel length. In the current study, we obtained a short pedicel mutant through EMS mutagenesis and discovered that the reduced cell number was the primary cause of the shortened pedicel. Upon analyzing the hormone content, we found that the level of trans zeatin in the long-pedicel material was significantly higher than that in the short-pedicel material. Further transcriptome sequencing analysis revealed that differentially expressed genes were enriched in cytokinin synthesis-related pathways. Based on these results, the present study concluded that cucumber pedicel length is regulated by genes related to the cytokinin synthesis pathway and that differences in length result from differences in zeatin content and cell number.
