Phylogenetic analysis of Demodex caprae based on mitochondrial 16S rDNA sequence.
Article in Parasitology research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Demodex caprae infests the hair follicles and sebaceous glands of goats worldwide, which not only seriously impairs goat farming, but also causes a big economic loss. However, there are few reports on the DNA level of D. caprae. To reveal the taxonomic position of D. caprae within the genus Demodex, the present study conducted phylogenetic analysis of D. caprae based on mt16S rDNA sequence data. D. caprae adults and eggs were obtained from a skin nodule of the goat suffering demodicidosis. The mt16S rDNA sequences of individual mite were amplified using specific primers, and then cloned, sequenced, and aligned. The sequence divergence, genetic distance, and transition/transversion rate were computed, and the phylogenetic trees in Demodex were reconstructed. Results revealed the 339-bp partial sequences of six D. caprae isolates were obtained, and the sequence identity was 100% among isolates. The pairwise divergences between D. caprae and Demodex canis or Demodex folliculorum or Demodex brevis were 22.2-24.0%, 24.0-24.9%, and 22.9-23.2%, respectively. The corresponding average genetic distances were 2.840, 2.926, and 2.665, and the average transition/transversion rates were 0.70, 0.55, and 0.54, respectively. The divergences, genetic distances, and transition/transversion rates of D. caprae versus the other three species all reached interspecies level. The five phylogenetic trees all presented that D. caprae clustered with D. brevis first, and then with D. canis, D. folliculorum, and Demodex injai in sequence. In conclusion, D. caprae is an independent species, and it is closer to D. brevis than to D. canis, D. folliculorum, or D. injai.
