Molecular Detection of Tick-Borne Rickettsial Pathogens Associated with the Arabian Camel (Camelus dromedarius) in Riyadh and the Eastern Region, Saudi Arabia.
Article in Acta parasitologica, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundIn Saudi Arabia, records on molecular identification of tick-borne infections in camels are relatively scarce; few molecular epidemiological studies have been conducted.
objectiveThis study aimed to find Anaplasma species and Piroplasma spp. in camels from Riyadh and the Eastern Region, Saudi Arabia. ANIMALS: A total of 1369 blood samples were collected from camels from Riyadh and the Eastern Region and analyzed for the DNA of Anaplasma and Piroplasma species by polymerase chain reaction (PCR).
resultsPiroplasma spp. infection was not observed in any of the blood samples. 616 camels (44.99%) were found to be positive for Anaplasma infection by PCR targeting the 16S rRNA and COX1 genes. Six Anaplasma sequences for the 16S rRNA gene (OK481101-OK481106) were deposited in GenBank and six for the COX1 gene (OK490994-OK490999). They showed 98.3% and 62.7% similarities with Anaplasma marginale (A. marginale) detected in Kenya and Brazil, respectively. Phylogenetic studies revealed that the 12 sequences reported in this study were closely related; they were found in the same cluster as A. marginale isolates previously recorded in South Africa, Brazil, USA, China, and Israel.
conclusionFinally, 12 Anaplasma sequences closely related to A. marginale were detected in camels in Riyadh and the Eastern Region, Saudi Arabia. Camels in these areas were confirmed to be free of Piroplasma.
