Estimating the seroprevalence of Mycobacterium bovis infection in a wild deer population in southwest England.

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
backgroundIn England, transmission of Mycobacterium bovis between cattle and certain species of free-roaming, wild deer has been implicated in some endemic bovine tuberculosis (bTB) regions. However, there are still data and knowledge gaps regarding the role of deer in the epidemiology of this disease. This paper presents the results of a serological survey to estimate the prevalence of M. bovis infection in a large wild deer population in the bTB high-risk area of southwest England.
methodsBlood samples were collected postmortem over a 12-month period from wild deer shot during annual population controls in the Exmoor area and tested for M. bovis serum antibodies. True seroprevalence of M. bovis infection in the study population was estimated by accounting for the imperfect diagnostic accuracy of the IDEXX test used.
resultsOverall, 432 individual animal samples were tested, predominantly from red deer (80.3%). Sixty-nine (16.0%) were seropositive, with the estimated true seroprevalence being 27.4% (95% confidence interval 19.9%-36.3%). Prevalence did not appear to differ between sexes or species. Few positive samples were observed in the youngest animals. LIMITATIONS: As convenience sampling of deer carcases was used, a degree of bias in the results cannot be excluded. Estimation of true seroprevalence was affected by the imperfect performance of the IDEXX test in deer.
conclusionsThis study provides valuable insight into M. bovis seroprevalence in this wild deer population, which is at the upper end of prevalence estimates reported in deer worldwide. Our results should be interpreted alongside other relevant information, including species-specific ecology, epidemiology and disease pathology, to inform potential transmission risks between cattle and wild deer.
