1 · What the graph read from it

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.

2 · The registry

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

purposeTheileria species are tick-borne, intracellular apicomplexan protozoan parasites that pose a significant threat to livestock health and productivity. Theileria orientalis, the etiological agent of oriental theileriosis, is a benign Theileria species with worldwide distribution, including Algeria, where investigations on its prevalence and genetic diversity in domestic ruminants are limited. This study aimed to investigate the molecular and phylogenetic profiles of Theileria spp. in Algeria.

methodsA total of 149 blood samples were collected from cattle, sheep, and goats in Bouira and Tizi-Ouzou regions. Molecular identification was performed using a PCR assay targeting the Cox3 and Tams1 genes. Positive samples were sequenced to assess their phylogenetic relationships.

resultsAnalysis of the Cox3 gene revealed an overall infection rate of 12.75% ± 2.73% (19/149), with all positive cases detected in cattle. Further analysis of the Tams1 gene identified Theileria annulata in 11.40% ± 5.10% (17/149) of the samples. Sequencing of two samples negative for T. annulata showed a 99.84% identity with Theileria orientalis.

conclusionsThis study reports the identification of a novel T. orientalis Cox3 haplotype in Algeria, emphasizing the need for further epidemiologic and phylogenetic analyses to understand better the distribution, diversity, and impact of this pathogen on livestock populations in the region.
