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
Avirulence of Magnaporthe grisea isolate CHL346 on rice cultivar GA25 was studied with 242 ascospore progenies derived from the cross CHL346 x CHL42. Segregation analysis of the avirulence in the progeny population was in agreement with the existence of a single avirulence (Avr) gene, designated as AvrPi15. For mapping the Avr gene, we developed a total of 121 microsatellite DNA markers [simple sequence repeat (SSR)], which evenly distributed in the whole-genome of M. grisea through bioinformatics analysis (BIA) using the publicly available sequence. Linkage analysis of the AvrPi15 gene with these SSR markers showed that six markers on chromosome 6, MS6-1, MS6-2, MS6-3, MS6-7, MS6-8 and MS6-10, were linked to the AvrPi15 locus. To further define the chromosomal location of the AvrPi15 locus, two additional markers, MS6-17 and STS6-6, which were developed based on the sequences of telomeric region 11 (TEL11), were subjected to linkage analysis. The results showed that MS6-17 and STS6-6 were associated with the locus by 3.3 and 0.8 cM, respectively. To finely map the Avr gene, two additional candidate avirulence gene (CAG) markers, CAG6-1 and CAG6-2, were developed based on the gene annotation of the sequence of TEL 11. Linkage analysis of the Avr gene with these two markers revealed that both of them completely cosegregated with the AvrPi15 locus. Finally, this locus was physically mapped into approximately 7.2-kb interval of the TEL11 by BIA using these sequence-ready markers. This is the key step toward positional cloning of the AvrPi15 gene.
