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 survey of Anaplasma species in small ruminants is still lacking in North African countries. In this study, the presence of A. phagocytophilum, A. phagocytophilum-related species, and A. ovis was investigated in a total of 563 healthy small ruminants (303 goats and 260 sheep), from 25 randomly selected flocks sampled in Tunisia. Anaplasma spp. and A. ovis overall infection rates were 95.0% and 93.8% in sheep and 69.6% and 65.3% in goats, respectively. A. phagocytophilum was not detected in any of tested animals. A total of 20 sheep (7.7%) and 144 goats (47.5%) were infected by Anaplasma strains genetically related to A. phagocytophilum. Both in sheep and goats A. ovis prevalence was higher in adults (≥2 years) than in young (<2 years) subjects (p = 0.001 and 0.002 for goats and sheep, respectively). In sheep, A. ovis prevalence was higher in ewes with respect to rams (p = 0.010). The A. ovis infection rate was significantly lower in goats of the local breed (p = 0.049) and it was higher in goats infested by ticks than in not infested animals (p = 0.005). Genetic analysis of the msp4 gene of A. ovis indicated the presence of strains shared by Tunisian sheep and goats. Sequence analysis and phylogenetic studies on the basis of the 16S rRNA gene provided evidence for the circulation of at least two different potentially novel species genetically related to A. phagocytophilum in Tunisian small ruminants. These findings cause concern about specificity of serological tests used for detection of A. phagocytophilum in ruminants and provide additional information for elucidating pathogenesis and molecular epidemiology of A. phagocytophilum and related species.
