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
Rice yellow mottle virus (RYMV) is the most damaging rice-infecting virus in Africa. However, few sources of high resistance and only a single major resistance gene, RYMV1, are known to date. We screened a large representative collection of African cultivated rice (Oryza glaberrima) for RYMV resistance. Whereas high resistance is known to be very rare in Asian cultivated rice (Oryza sativa), we identified 29 (8%) highly resistant accessions in O. glaberrima. The MIF4G domain of RYMV1 was sequenced in these accessions. Some accessions possessed the rymv1-3 or rymv1-4 recessive resistance alleles previously described in O. glaberrima Tog5681 and Tog5672, respectively, and a new allele, rymv1-5, was identified, thereby increasing the number of resistance alleles in O. glaberrima to three. In contrast, only a single allele has been reported in O. sativa. Markers specific to the different alleles of the RYMV1 gene were developed for marker-assisted selection of resistant genotypes for disease management. In addition, the presence of the dominant susceptibility allele (Rymv1-1) in 15 resistant accessions suggests that their resistance is under different genetic control. An allelism test involving one of those accessions revealed a second major resistance gene, i.e., RYMV2. The diversity of resistance genes against RYMV in O. glaberrima species is discussed in relation to the diversification of the virus in Africa.
