Environmental surveillance for human astrovirus in Shandong Province, China in 2013.
Article in Scientific reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Human astroviruses (HAstVs) are one of the leading viral agents of acute gastroenteritis. However, there is limited information on HAstVs in China. Here, we describe the molecular characterization of HAstVs in Shandong, China via sewage surveillance. A total of 23 sewage samples were collected from sewage treatment plants in the cities of Jinan and Linyi in 2013. After concentration via adsorption-elution method, 9 samples (39.1%) were positive by reverse transcription PCR (RT-PCR) for the presence of the 719-nt HAstV nucleotide sequence. Genetic cloning and sequencing were performed on positive PCR products, and 26 HAstV sequences were obtained. Phylogenetic analysis on these sequences revealed 4 genotypes (HAstV-1, -2, -4 and -5), with HAstV-1 and -5 as the most common genotypes in Jinan and Linyi, respectively. Homologous comparison revealed Shandong sequences had relatively less genetic divergence among themselves than with foreign sequences. This study represents the first effort to investigate the genotypes and molecular epidemiology of HAstVs via sewage surveillance in China. The high detection rate in this study reflects that HAstVs circulated at a relatively high frequency in the local population, and demonstrates that environmental surveillance is an effective method in investigating circulating HAstVs.
