Ticks and rickettsial infection in the wildlife of two regions of the Brazilian Amazon.
Article in Experimental & applied acarology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 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
During 2009-2012, wild animals and their ticks were sampled in two areas within the Amazon biome of Brazil, in the states of Mato Grosso and Pará. Animal tissues, blood, and ticks were molecularly tested for Rickettsia and Coxiella DNA. A total of 182 wild animals were sampled, comprising 28 mammalian, five avian, and three reptilian species. Animal tissues or blood were all negative for Rickettsia or Coxiella DNA. A total of 454 ticks (22 larvae, 226 nymphs, 127 males, 79 females) were collected from 52 (28.6%) animals, and identified into 15 species: Amblyomma cajennense, A. naponense, A. humerale, A. nodosum, A. goeldii, A. oblongoguttatum, A. longirostre, A. calcaratum, A. coelebs, A. pacae, A. geayii, A. rotundatum, A. auricularium, A. ovale, and Haemaphysalis juxtakochi. While no Coxiella DNA was identified in ticks, six Rickettsia species were detected in the ticks. "Candidatus Rickettsia amblyommii" was the most common agent, detected in four tick species, A. cajennense, A. auricularium, A. longirostre, and A. humerale. The second most common agent, R. bellii, was detected in A. humerale and A. naponense. Rickettsia rhipicephali was detected in H. juxtakochi, and R. felis in A. humerale. Two possible new Rickettsia species were detected in A. naponense ticks, namely, a novel spotted fever group agent close-related to R. africae in Pará, and a novel Canadensis group agent in Mato Grosso. Results of the present study expand our knowledge on the tick fauna, and on the yet infantile knowledge of tick-borne rickettsiae in the Amazon biome.
