Molecular identification and genetic analysis of Rhipicephalus sanguineus sensu lato of dogs in Nigeria, West Africa.
Article in Experimental & applied acarology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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 brown dog tick, Rhipicephalus sanguineus sensu lato, is a ubiquitous and taxonomically controversial pest of dogs with immense veterinary and public health significance. Genetic analyses of specimens from various geographical origins reveal intraspecific diversity within the taxon. Little information is available on the genetic characteristics of R. sanguineus s.l. in Nigeria, West Africa. In this study, 460 bp of the mitochondrial 16S rDNA gene of R. sanguineus s.l. collected from dogs in different ecological zones of Nigeria was amplified, sequenced and characterized. Phylogenetic and pairwise analyses were used to compare the sequences generated in this study to each other and to sequences in GenBank. The sequences in this study were highly similar (>98%) to each other and clustered with sequences of the R. sanguineus s.l. tropical lineage in GenBank. None of the sequences in this study clustered with the 'southeastern Europe' or temperate lineage. The mean intraspecific divergence among R. sanguineus s.l. in this study was 1.7% (range: 0-8.0%). Furthermore, the sequences in this study showed mean divergence of 1.5% (0-10%), 5.0% (3.8-13.9%) and 9.7% (6.9-19.8%) from sequences of the tropical, southeastern Europe and temperate lineages, respectively. Interestingly, sequences in this study showed a mean divergence of 9.3% (1.0-17.8%) from the Rhipicephalus sp. morphotype 4 (GenBank acc. nr. KC243850) earlier identified from cattle in Nigeria, suggesting diversity in this taxon in Nigeria. Further studies are needed to elucidate the veterinary and public health significance of R. sanguineus s.l. in Nigeria taking into cognizance the existence of intraspecific variation in vector competence.
