The position of repetitive DNA sequence in the southern cattle tick genome permits chromosome identification.
Article in Chromosome research : an international journal on the molecular, supramolecular and evolutionary aspects of chromosome biology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
Fluorescent in-situ hybridization (FISH) using meiotic chromosome preparations and highly repetitive DNA from the southern cattle tick, Rhipicephalus microplus, was undertaken to investigate genome organization. Several classes of highly repetitive DNA elements were identified by screening a R. microplus bacterial artificial chromosome (BAC) library. A repeat unit of approximately 149 bp, RMR-1 was localized to the subtelomeric regions of R. microplus autosomes 1-6 and 8-10. A second repeat unit, RMR-2 was localized to the subtelomeric regions of all autosomes and the X chromosome. RMR-2 was composed of three distinct repeat populations, RMR-2a, RMR-2b and RMR-2c of 178, 177 and 216 bp in length, respectively. Localization of an rDNA probe identified a single nucleolar organizing region on one autosome. Using a combination of labeled probes, we developed a preliminary karyotype for R. microplus. We present evidence that R. microplus has holocentric chromosomes and explore the implications of these findings for tick chromosome biology and genomic research.
