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
key messageThe overexpression of HaCYC2c and its regulation on HaNDUA2 through transcriptional recognition are important for regulating the heteromorphous development and functional differentiation of ray and disc florets in sunflower. Flower symmetry is closely related to pollinator recruitment and individual fecundity for higher plants and is the main feature used to identify flower type in angiosperms. In sunflower, HaCYC2c regulates floral organ development and floral symmetry, but the specific detail remains unclear. In this study, sunflower long petal mutant (lpm) with HaCYC2c insertion mutation was used to investigate the regulating role of HaCYC2c in the morphogenesis of florets and the transformation of floral symmetry through phenotype, transcriptome, qRT-PCR, and possible protein-gene interactions analyses. Results showed that HaCYC2c was overexpressed after an insertion into the promoter region. This gene could recognize the cis-acting element GGTCCC in the promoter region of HaNDUA2 that might regulate HaNDUA2 and affect other related genes. As a consequence, the abnormal elongation of disc petals and the degradation of male reproductive system occurred at the early development of floral organ in sunflower. Furthermore, this insertion mutation resulted in floral symmetry transformation, from actinomorphy to zygomorphy, thereby making the tubular disc florets transformed into ray-like disc florets in sunflower lpm. The findings suggested that the overexpression of HaCYC2c and its control of HaNDUA2 through transcriptional recognition might be an important regulating node of the heteromorphous development and functional differentiation for ray and disc florets in sunflower. This node contributes to the understanding of the balance between pollinator recruitment capacity of ray florets and fertility of disc florets for the optimization of reproductive efficiency and enhancement of species competitiveness in sunflower.
