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
Bovine leukemia virus (BLV) is a causative agent of enzootic bovine lymphoma (EBL). BLV is prevalent worldwide, and ten genotypes have been classified based on the sequence of the envelope glycoprotein (gp51) gene. In this study, we present a simple and generally applicable PCR restriction fragment length polymorphism (PCR-RFLP) method to identify BLV genotypes. While the genotyping results obtained by previously described PCR-RFLP methods matched only 78.96% to the results of phylogenetic analysis, we demonstrated that our PCR-RFLP method can identify 90.4% of the sequences available in the database in silico. The method was validated with 20 BLV sequences from EBL tumor tissues and 3 BLV sequences from blood of BLV infected cattle, and was found to show high specificity. We utilized this method to determine genotypes of blood samples from 18 BLV seropositive cattle in Kanagawa and Niigata, as well as 12 EBL cattle in Chiba, Japan. Our analysis with the modified PCR-RFLP detected two genotypes, Genotypes 1 and 3. Genotype 1 was detected as the main genotype, while Genotype 3 was sporadically observed. This technique can be used as a reliable system for screening a large number of epidemiological samples.
