Identification of Anaplasma phagocytophila (formerly Ehrlichia phagocytophila) variants in blood from sheep in Norway.
Article in Journal of clinical microbiology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 34 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
A total of 41 blood samples were collected from 40 Anaplasma phagocytophila-infected sheep in 11 sheep flocks from four different counties of southern Norway. The presence and nature of the Anaplasma species were identified by microscopic detection of morulae, PCR, reverse line blot hybridization, and 16S rRNA gene sequencing. A. phagocytophila was identified in all of the samples, and sequencing of the 16S rRNA gene revealed the presence of four variants of A. phagocytophila. Two of these variants have been described before, but two were newly identified 16S rRNA variants of this species. A. phagocytophila variant 1 was found in nine flocks, A. phagocytophila variant 2 was found in four flocks, the A. phagocytophila prototype was found in two flocks, and A. phagocytophila variant 5 was found in one flock. In two flocks, some sheep were infected with A. phagocytophila variant 1, whereas others were infected with A. phagocytophila variant 2, and in three animals a double infection with two variants was registered. Analyses of the blood samples revealed that blood from sheep infected with A. phagocytophila variant 2 contained nearly twice as many neutrophils and eight times as many Anaplasma-infected neutrophils as blood from sheep infected with the A. phagocytophila variant 1. Furthermore, only 43% of the A. phagocytophila variant 2-infected sheep displayed antibody responses in an immune fluorescence assay, whereas 93% of the sheep with the A. phagocytophila variant 1-infected sheep were seropositive.
