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 messageThree genes designated DvLox, Pm21#4, and Pm21#4-H identified in a wheat-Dasypyrum villosum#4 T6V#4S·6DL translocation line Pm97033 conferred wheat for powdery mildew resistance. Powdery mildew (PM) caused by Blumeria graminis f. sp. tritici (Bgt) is one of the most devastating diseases in wheat. To date, only a few genes conferring resistance to wheat PM are cloned. Dasypyrum villosum is a wild relative of wheat, which provides Pm21 conferring wheat immunity to PM. In this study, we obtained many differentially expressed genes (DEGs) from a wheat-D. villosum#4 T6V#4S·6DL translocation line Pm97033 using RNA-sequencing. Among them, 7 DEGs associated with pathogen resistance were up-regulated in front of Bgt infection. Virus-induced gene silencing and transformation assays demonstrated that two of them, DvLox and Pm21#4 encoding a lipoxygenase and a encoding coiled-coil/nucleotide-binding site/leucine-rich repeat resistance protein, conferred wheat PM resistance. The transgenic wheat plants expressing DvLox enhanced PM resistance, and the transgenic wheat plants expressing Pm21#4 showed PM immunity. The Pm21#4-silenced Pm97033 plants by the cluster regularly interspaced short palindromic repeats-associated endonuclease (CRISPR/Cas9) system were susceptible to PM. Thus, Pm21#4 is a key gene contributing PM immune resistance in Pm97033. Constitutively expression of Pm21#4-H, which is silenced in Pm97033 and D. villosum#4, endowed a PM-susceptible wheat variety Fielder with PM immune resistance.
