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

Tropical theileriosis is a serious animal disease transmitted by tick vectors. The agents of theileriosis are obligate intracellular parasites that cause mild to severe disease in the mammalian host. Tropical theileriosis has been recognized as a burden to the development of the dairy industry in Sudan and causes major economic losses. However, knowledge about the distribution of Theileria spp. in Sudan and the extent of sequence variation within the 18S rRNA gene is currently unknown. The aim of this study was to determine the diversity of Theileria spp. using 18S rRNA-based PCR to detect parasites in cattle followed by cloning and sequencing. We observed an overall prevalence rate of 63% hemoparasite infection in cattle from Sennar state. A subset of samples was used for cloning and sequencing of the 18S rRNA gene. Nineteen of 44 animals were co-infected with more than one species of Theilera. Phylogenetic analysis revealed three Theileria spp. that were predominant in cattle including pathogenic T. annulata and apathogenic T. velifera and T. mutans. The present study provides information regarding the prevalence of theileriosis in Sudan and will help to design strategies to control it. Additionally, more study is needed to determine tick vector competence and degree of coinfection with multiple Theileria spp. in Sudan. This represents the first molecular phylogeny report to identify Theileria spp. in cattle from Sudan.
