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

backgroundTicks are responsible for the transmission of various viral, bacterial, and protozoal pathogens through their mouthparts while feeding on the blood of the host. Owing to the increasing trend of tick-borne diseases, they are considered major emerging public health issues throughout the globe. In South Asia, the major important canine tick-borne pathogens are Babesia spp., Hepatozoon canis, Ehrlichia canis, Anaplasma platys, and Borrelia burgdorferi. Among various diagnostic tests, molecular techniques are considered the gold standard for the detection of tick-borne diseases. A total of 341 canine blood samples were collected from Kathmandu, Pokhara, and Chitwan, Nepal. The collected blood samples were subjected to hematological analysis, DNA extraction, and conventional polymerase chain reaction to detect the presence of tick-borne pathogens. Additionally, a total of 219 ticks were collected from the sampled dogs and identified via morphometry.

resultsPCR assays revealed four tick-borne pathogens, Babesia spp., Ehrlichia canis, Hepatozoon canis, and Anaplasma platys, with prevalence rates of 26.09%, 5.87%, 3.52%, and 2.93%, respectively, and an overall prevalence of 31.09% (95% CI: 26.27-36.34%). However, this study could not identify the prevalence of Borrelia burgdorferi. During the hematological analysis, anemia and thrombocytopenia in the sampled dogs were significantly associated with the presence of Babesia spp. (p < 0.01 and p < 0.05, respectively), lymphocytosis was significantly associated with Hepatozoon canis (p < 0.001), and thrombocytopenia was significantly associated with Ehrlichia canis (p < 0.05). Among the ticks infesting dogs at the study sites, the Rhipicephalus genus was the most prevalent, followed by Haemaphysalis and Dermacentor, with an overall tick infestation rate of 27.86%. Geographic location, type of dog (stray or pet), and body condition score were determined as potential risk factors by multiple logistic regression analysis (OR = 0.40, 2.16, 0.73; p < 0.01, p < 0.05, p < 0.05, respectively) for the presence of canine tick-borne pathogens.

conclusionsThis study identified at least four species of canine tick-borne pathogens and three genera in dogs from study area. Findings of this study highlights the importance of robust treatment, control and preventive measures to mitigate the transmission of these pathogens.
