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

Q fever, first described in 1937, is a worldwide zoonosis caused by Coxiella burnetii that has long been considered an under-reported and under-diagnosed illness. In China, the disease was initially reported in 1950 and in the last 25 years (1989-2013) there have been 29 reports on Q fever in China, nearly half of which were in the last 5 years. These publications have largely been in Chinese and in this review we summarize their findings to enable a better understanding of Q fever in China. The overall prevalence of C. burnetii infections in the reports is 10% (1139/11 209) in people, 15% (288/1918) in cattle and 12% (176/1440) in goats. These infections occurred widely in China with positive people and/or animals reported in 64 cities/municipalities from 19 provinces, particularly those in the eastern, western and northern areas. Cattle and goats had the highest seroprevalences of all the domestic animals studied and a wide variety of ticks were found to be infected. Mice were also commonly infected and had high copy numbers of C. burnetii DNA, suggesting they might be important in the epidemiology of Q fever in China.
