Molecular characterization of Blastocystis species in Oregon identifies multiple subtypes.
Article in Parasitology research, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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 association of Blastocystis species infections with gastrointestinal symptoms in humans is clouded by the variable presentation of disease and multiple lineages of the parasite that can infect humans and other animals. It has long been suspected that certain subtypes of Blastocystis may be more or less pathogenic, be restricted to certain hosts, or have limits to their geographic distribution. In the state of Oregon, USA, Blastocystis spp. are the most commonly encountered parasites in fecal specimens submitted for diagnostic evaluation, yet the diversity of subtypes is unknown. In this study, fecal samples were collected from individuals experiencing symptoms associated with blastocystosis and analyzed by polymerase chain reaction for presence of the parasite and DNA sequenced for subtyping. Five of 19 individuals tested positive for the parasite, all of which were also positive by previous ova and parasitology examination. DNA sequencing of the small subunit ribosomal DNA and elongation factor 1 alpha gene followed by phylogenetic subtyping identified five unique subtypes, representing Blastocystis subtypes 1, 2, 3, 4, and 8. No symptoms were consistently associated with presence or absence of infection, although abdominal pain and fatigue were reported by all infected individuals. Multiple subtypes are indicative of multiple sources of infection, suggesting more extensive surveys are required to understand the transmission of this parasite.
