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

Background: Hemomycoplasmosis caused by Hemotropic mycoplasmas, or Hemoplasma, which were previously classified as Eperythrozoon spp., are uncultivable parasites that infect the cell wall of erythrocytes in many susceptible mammals, including cattle, buffalo, goats, sheep, horses, cats, dogs, and even camels, and can be transmitted to humans. Aim: The purpose of the present work is to display and evaluate the different diagnostic criteria for detecting the most precise method for diagnosing Hemomycoplasma in horses. Methods: Different diagnostic methods were used to diagnose equine Hemomycoplasmosis caused by Results: cytological diagnosis revealed an infection rate of 88% (88/100), while the molecular diagnosis via qPCR confirmed infection in 79% (79/100) of the samples. The agreement between the two diagnostic methods was analyzed using Cohen's Kappa statistic. The observed agreement was 91% (91/100), and the expected agreement by chance was 72.04%. The calculated Kappa coefficient was κ = 0.678 [95%, (confidence interval)], indicating substantial agreement between cytological and qPCR diagnoses according to the Landis and Koch benchmark. The findings also showed that infected horses exhibit significant differences in the acute phase response; additionally, dead carcasses displayed general emaciation, paleness of internal organs, obvious splenomegaly, and enlarged liver, kidneys, and heart, which showed white patches. Furthermore, histopathological changes indicate degeneration and necrosis in cardiac muscles, besides atrophic glomeruli, accompanied by the dilatation of renal tubules in the kidneys, as well as a marked reduction in the proportion of white pulp of splenic tissue and degenerative changes in the cytoplasm of hepatocytes, accompanied by nuclear alterations characterized by loss of chromatin content in the hepatic tissue. Conclusion: It was concluded that evaluating different tests for diagnosing equine Hemomycoplasmosis is very important to identify the most accurate one and use it confidently in the future. Additionally, although the diagnostic criteria and accuracy of each test vary, each test has its advantages and disadvantages. Moreover, Cytological diagnosis is still advised for field screening, whereas qPCR is for confirmatory diagnosis.
