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

backgroundCoxiella burnetii is a bacterial pathogen that can cause abortion and reproductive disease in livestock. In the UK, C. burnetii affects many dairy cattle herds, although the infection dynamics are poorly understood. Our study was performed to investigate infection patterns within a dairy cattle herd in Scotland that had experienced stillbirths attributed to C. burnetii infection.

methodsDifferent management groups within the affected herd were sampled. Serology and qPCR testing of vaginal swabs were performed to investigate infection status. Regression analyses were performed to evaluate associations between diagnostic results and variables describing calving status and farm site.

resultsC. burnetii infection was detected in all management groups within the herd. The highest seroprevalence was detected in pre-calving heifers (78.6%) and the highest bacterial loads were detected in post-calving animals. LIMITATIONS: These data represent a sample from one farm and testing for a single pathogen shedding route, which limits the generalizability of our findings.

conclusionsC. burnetii infection is widespread within this affected herd. Marked differences were observed between the management groups, which may be explained by variables including pregnancy stage or environmental factors. Further work is needed to understand the implications of these results for the wider UK dairy sector.
