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
The identification and utilization of broad-spectrum resistance genes have been proven the most effective and economical approach to control rice blast disease. To understand the molecular mechanism of broad-spectrum resistance to rice blast, we conducted genetic and fine mapping analysis of the blast resistance gene in a Chinese rice variety: Gumei 4 (GM4) identified with broad-spectrum resistance and used in rice breeding for blast resistance for more than 20 years. Genetic and mapping analysis indicated that blast resistance to nine isolates of different Chinese races in GM4 was controlled by the same dominant locus designated as Pigm(t) that was finely mapped to an approximately 70-kb interval between markers C5483 and C0428 on chromosome 6, which contains five candidate NBS--LRR disease resistance genes. The allelism test showed that Pigm(t) was either tightly linked or allelic to Pi2 and Pi9, two known blast resistance genes. Mapping information also indicated that another blast resistance gene Pi26(t) might also be located at the same region. Candidate genes were identified by sequence analysis of the Nipponbare and Pi9 locus and the corresponding region in GM4. Sequence divergence of candidate genes was observed between GM4 and model varieties Nipponbare and 9311, and Pi9. Our current study provides essential information and new genetic resource for the cloning of functional resistance gene(s) and for marker-assisted selection in rice breeding for broad-spectrum blast resistance.
