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
Seed storage proteins (SSPs) are determinants of wheat end-product quality. SSP synthesis is mainly regulated at the transcriptional level. Few transcriptional regulators of SSP synthesis have been identified in wheat and this study aims to identify novel SSP gene regulators. Here, the R2R3 MYB transcription factor TuODORANT1 from Triticum urartu was found to be preferentially expressed in the developing endosperm during grain filling. In common wheat (Triticum aestivum) overexpressing TuODORANT1, the transcription levels of all the SSP genes tested by RNA-Seq analysis were reduced by 49.71% throughout grain filling, which contributed to 13.38%-35.60% declines in the total SSP levels of mature grains. In in vitro assays, TuODORANT1 inhibited both the promoter activities and the transcription of SSP genes by 1- to 13-fold. The electrophoretic mobility shift assay (EMSA) and ChIP-qPCR analysis demonstrated that TuODORANT1 bound to the cis-elements 5'-T/CAACCA-3' and 5'-T/CAACT/AG-3' in SSP gene promoters both in vitro and in vivo. Similarly, the homolog TaODORANT1 in common wheat hindered both the promoter activities and the transcription of SSP genes by 1- to 112-fold in vitro. Knockdown of TaODORANT1 in common wheat led to 14.73%-232.78% increases in the transcription of the tested SSP genes, which contributed to 11.43%-19.35% elevation in the total SSP levels. Our data show that both TuODORANT1 and TaODORANT1 are repressors of SSP synthesis.
