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
Eyespot is an economically important fungal disease of wheat and other cereals caused by two fungal species: Oculimacula yallundae and Oculimacula acuformis. However, only two eyespot resistance genes have been characterised and molecular markers made available to plant breeders. These resistances are Pch1, introduced into wheat from the relative Aegilops ventricosa, and Pch2, originally identified in the cultivar Cappelle Desprez (CD). There are drawbacks associated with both resistances; Pch1 is linked to deleterious traits carried on the Ae. ventricosa introgression and Pch2 has been shown to have limited effectiveness. An additional resistance has been reported on chromosome 5A of CD that confers resistance to eyespot in adult plants. In the present study, we demonstrate that resistance on this chromosome is effective against both O. yallundae and O. acuformis eyespot pathogens and confers resistance at both seedling and adult plant stages. This resistance was mapped in both seedling bioassays and field trials in a 5A recombinant population derived from a cross between CD and a CD single chromosome substitution line carrying 5A from the susceptible line Bezostaya. The resistance was also mapped using seedling bioassays in a 5A recombinant population derived from a cross between the susceptible line Chinese Spring (CS) and a single chromosome substitution line carrying 5A from CD. A single major QTL on the long arm of chromosome 5A was detected in all experiments. Furthermore, the SSR marker Xgwm639 was found to be closely associated with the resistance and could be used for marker-assisted selection of the eyespot resistance by plant breeders.
