Prevalence and phylogenetic analysis of the isolated type I porcine reproductive and respiratory syndrome virus from 2007 to 2008 in Korea.
Article in Virus genes, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 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
The first Korean strain of porcine reproductive and respiratory syndrome virus (PRRSV) was isolated in 1997, and it exhibited high similarity to strain VR-2332 (type II PRRSV; North American type). Recently, however, infection with type I PRRSV (European type) has also been reported in Korea. To date, preliminary data about type I PRRSV prevalence in Korea have not been reported. Here, using reverse transcriptase (RT)-PCR, we analyzed 383 archived field samples from 101 pig farms in Korea that were collected from 2007 to 2008. We identified 155 samples from 68 farms that were positive for PRRSV. Fifty-one samples (51/155; 32.9%) and 20 farms (20/68; 29.4%) were type I PRRSV-positive/type II PRRSV-negative. Furthermore, we tried to isolate the type I PRRSV from positive samples and seven type I PRRSV were isolated using PAM. The phylogenetic analysis using the type I PRRSV isolates (7 isolates) was performed based on open reading frame (ORF)5 (accession numbers GU325642 to GU325648) and ORF7 (accession numbers GU325635 to GU325641). In the phylogenetic study, seven type I PRRSV isolates were closely related with panEuropean based on ORF7, while they were genetically distinct from Lelystad virus and made a unique clade based on ORF5. The results of this study demonstrate that infection with type I PRRSV is not uncommon in Korean pig farms, which suggests that diagnosis and control of type I PRRSV should be considered in Korea. A new approach to vaccination against, and epidemiological analysis of, Korean PRRSV is urgently needed.
