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
Cytoplasmic male sterility (CMS) and its fertility restoration (Rf) genes are critical tools for hybrid seed production to utilize heterosis. In sunflower, CMS PET1 and the associated Rf gene Rf (1) is the only source extensively used in commercial hybrid production. The objective of this research was to develop new sources of CMS and fertility restorers to broaden the genetic diversity of hybrid seed production. We identified a new type of CMS, named as CMS GIG2, from an interspecific cross between Helianthus giganteus accession1934 and H. annuus cv. HA 89. Based on reactions to a set of standard Rf testers, CMS GIG2 is different from all previously reported CMS types, including the CMS GIG1 from another H. giganteus accession. We also identified an Rf gene for CMS GIG2 from wild species H. maximiliani accession 1631. The CMS GIG2 and its restoration gene were introduced into HA 89 background through recurrent backcross and single plant selection techniques. Genetic analysis revealed that the CMS GIG2-Rf system is controlled by a completely dominant gene, named as Rf (4), and the gene additive and dominance effects were estimated as 39.9 and 42.2%, respectively, in the HA 89 background. The gene Rf (4) was mapped onto linkage group 3 with simple sequence repeat (SSR) markers and RFLP-derived STS-marker, and is about 0.9 cM away from the SSR marker ORS1114 based on a segregation population of 933 individuals. The CMS GIG2-Rf (4) system tagged by molecular markers provides an alternative genetic source for hybrid breeding in the sunflower crop.
