Evaluation of associations among Coxiella burnetii and reproductive abnormalities in cats.
Article in Journal of feline medicine and surgery, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
objectivesCoxiella burnetii is an obligate intracellular bacterium that is found worldwide, is associated or suggested to be associated with reproductive abnormalities in a number of species including cats, and is the cause of Q fever in humans. In a previous study, C burnetii DNA was amplified from the uterine tissues of 8.5% of client-owned cats in the USA but reproductive history was unknown and histopathological examination was not performed. In this study, uterine tissues of 26 normal cats and 11 cats with histopathological evidence of uterine disease or other reproductive abnormalities were evaluated for the presence of C burnetii.
methodsA PCR assay that amplifies the repetitive transposon-like region (Trans 1 and 2) and a PCR assay that amplifies the IS-1111-insertion sequence (IS-1111) were optimised and applied to the DNA extracts. The sensitivity threshold of both PCR assays was 12 pg/µl. Positive samples were evaluated for the presence of the organism using immunohistochemistry performed on paraffin-embedded tissue.
resultsAmplicons of the expected size developed in three samples (one from a cat with reproductive abnormalities) in the IS-1111 assay; however, there was not enough DNA for sequence analysis. Immunohistochemical analysis was used to further evaluate these three samples and was negative for C burnetii. While C burnetii could not be confirmed by sequence analysis or immunohistochemistry, the PCR positive prevalence rate (8.1%) was similar to that published previously. CONCLUSIONS AND RELEVANCE: Biosafety precautions should be taken when working with cats that are aborting or parturient. Further research should be performed to evaluate the role that C burnetii may play in reproductive abnormalities in cats.
