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
backgroundAuxin response factors (ARFs) are plant-specific transcription factors that are crucial for flower development, lateral root formation, leaf senescence, and fruit ripening. Information on the ARF family genes in tetraploid potato remains unidentified.
resultsIn this study, we identified 92 StARF genes including alleles in the tetraploid potato genome (C88.v1), classified into four subfamilies, and unevenly distributed across 48 chromosomes. The promoter regions contained numerous light, plant hormones, and stress response elements, including those for low-temperature, drought, and anaerobic-induction cis-elements. Collinearity analysis suggested that StARF family members amplification results from whole genome and segmental duplications. Tissue-specific expression patterns manifested in most StARF family genes. RNA-seq data and WGCNA analysis of two tetraploid potato varieties with different-colored tuber flesh identified 11 differentially expressed StARF genes correlated with key anthocyanin synthesis genes. Protein-protein interaction predictions highlighted StARF23-1 as a potential key regulator of the anthocyanin biosynthesis pathway, warranting further investigation.
conclusionsOverall, our study comprehensively analyzes the StARF gene family in tetraploid potato and identifies candidate genes linked to anthocyanin synthesis, providing a foundation for future research on the regulatory role of StARF transcription factors in colored potato anthocyanin biosynthesis.
