"Candidatus Neoehrlichia mikurensis" in Ixodes ricinus ticks collected near the Arctic Circle in Norway.
Article in Parasites & vectors, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
background"Candidatus Neoehrlichia mikurensis" is a gram-negative bacterium belonging to the family Anaplasmataceae that, in Europe, is transmitted by Ixodes ricinus ticks. "Candidatus N. mikurensis" can cause a severe systemic inflammatory syndrome, neoehrlichiosis, mostly in persons with other underlying diseases. To date, "Ca. N. mikurensis" has been found in ticks in different countries in Asia and Europe, but never as far north as at the Arctic Circle.
methodsA total of 1104 I. ricinus ticks collected from vegetation and from animals in northern Norway (64-68°N) were analysed for the prevalence of "Ca. N. mikurensis". Of them, 495 ticks were collected from vegetation by flagging and 609 ticks were collected from dogs and cats. Total nucleic acid extracted from the ticks were converted to cDNA and analyzed with real-time PCR targeting the 16S rRNA gene of "Ca. N. mikurensis". Positive samples were further analysed by nested PCR and sequencing.
results"Candidatus N. mikurensis" was detected in 11.2% of all collected I. ricinus ticks in northern Norway. The prevalence differed between ticks collected from vegetation (18.2%; 90/495) compared to ticks collected from dogs and cats (5.6%; 34/609). The ticks from dogs and cats were collected in Brønnøy area and seven additional districts further north. The prevalence of "Ca. N. mikurensis" in these ticks differed between geographical localities, with the highest prevalence in the Brønnøy area.
conclusionsThe detection of "Ca. N. mikurensis" in I. ricinus ticks from the Arctic Circle in northern Norway indicates potential risk for tick-bitten humans at this latitude to be infected with "Ca. N. mikurensis".
