A H9N2 Human Case and Surveillance of Avian Influenza Viruses in Live Poultry Markets - Huizhou City, Guangdong Province, China, 2021.
Article in China CDC weekly, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
What is already known about this topic?: An increasing number of human infected avian influenza A (H9N2) cases have been reported. In 2021, 11 human infections with influenza A virus subtype H9N2 (A/H9N2) have been reported in China. What is added by this report?: A new case of H9N2 that occurred in April 2021 in Huizhou City, Guangdong Province, China, was reported in this study. Epidemiological and laboratory information of the case and routine influenza surveillance data of avian influenza A were presented in this report. What are the implications for public health practice?: The emergence of a human infected with Avian Influenza Virus H9N2 demonstrates that there is an urgent need to strengthen the surveillance of influenza-like illness and live poultry market.
