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

Theileria annulata is an intracellular parasite that causes active and latent forms of bovine theileriosis. Diagnosis of the disease is primarily based on traditional methods such as microscopy, however, PCR based methods have proven to be superior in the absence of clear disease symptoms. However, diagnosis is difficult in cases of lower parasitaemia by conventional PCR. Hence, a rapid and sensitive method which can detect early infection and low parasite load is required. Therefore, we have developed an absolute quantification based real-time PCR (qPCR) assay. Reference standard curve using recombinant plasmids of a host (hprt) and a parasite gene (tasp) was constructed, and the assay was initially standardised using in vitro T. annulata cell lines. Further, 414 blood samples from suspected theileriosis cases were also evaluated using qPCR. The assay can estimate host to parasite ratios, calculate parasitaemia and treatment effectiveness in the clinical cases of theileriosis. In comparison with the conventional PCR results, 44 additional positive cases were found. Therefore, the assay holds importance in a clinical setting due to its ability to quantify the parasite load in clinical samples. It may be further used in distinguishing active and latent theileriosis infections and detection of drug resistance in the field.
