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
Introduction: Single-cross hybrids are the predominant type of cultivar planted by maize growers worldwide. The clear understanding of both the inheritance of target traits and the heterotic patterns of breeding germplasm is essential for the development of heterotic and high-yielding single-cross hybrids in maize breeding programs. Therefore, our objectives were to determine the inheritance of agronomic traits in improved tropical maize germplasm; estimate the general and specific combine abilities (GCA and SCA) effects for these traits among 15 selected inbred lines; group these lines into heterotic groups using two approaches; and identify high-yielding hybrids derived from these lines. Methods: We evaluated 105 F Results and discussion: We found that the inheritance of most traits is predominantly governed by additive gene action, whereas grain yield is largely modulated by non-additive gene action in our set of selected inbred lines of tropical maize. The lines VML016, VML062, VML081, VML083 and VML131 are promising for simultaneously improving GY and reducing cycle and plant stature, whereas the VML105 and VML157 should be used to reduce cycle and increase grain yield, respectively, in our maize breeding program. Both the genetic distance among lines and the SCA effects for GY are effective for grouping the improved breeding lines into genetically distinct groups. Also, molecular makers should be employed to support the allocation of inbred lines into heterotic groups and aid in the selection of the best parental combinations for the development of breeding populations and hybrids in improved tropical maize germplasm. Finally, we identified 13 outstanding experimental hybrids that must be evaluated to confirm the consistence and stability of their yield performance across a wider range of environments and management conditions in southeastern Brazil for future release and commercialization.
