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
Chromosome karyotyping analysis is particularly useful in determining species relationships and the origin of polyploid species. Identification of individual chromosomes is the foundation for karyotype development. For Fragaria (strawberry) species, definitive identification of the individual chromosomes is extremely difficult because of their small size and similar shape. Here, we identified all chromosomes for 11 representative Fragaria species with different ploidy using a set of oligonucleotide-based probes developed in Fragaria vesca. Comprehensive molecular cytogenetic karyotypes were established based on the individually identified chromosomes. In addition, we used oligo probes to assign the 5S and 45S rDNA loci to specific chromosomes in 16 Fragaria species. We found that these Fragaria species maintained a remarkably conserved karyotype. No inter-chromosomal structural rearrangements at the cytological level were observed in any of the chromosomes among these species. Despite karyotypic stability and similarity, variations in the signal intensity of oligo probes were observed among the homologous chromosomes in several polyploid species. Moreover, most Fragaria species also showed differences in the distribution patterns of 45S and 5S rDNA. These data provide new insights into the origins of several polyploid Fragaria species.
