Molecular subtyping of Blastocystis sp. isolates from symptomatic patients in Italy.
Article in Parasitology research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 42 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
Blastocystis sp. is the most common eukaryotic parasite in the intestinal tract of humans. Due to its potential impact in public health, we determined the Blastocystis sp. subtypes (STs) and their relative frequency in symptomatic patients living in or in the vicinity of two Italian cities (Rome and Sassari). A total of 34 Blastocystis sp. isolates corresponding to 26 single and 4 mixed infections were subtyped using partial small subunit ribosomal RNA gene sequencing. From this molecular approach, the ST distribution in the present Italian population was as follows: ST3 (47.1%), ST2 (20.6%), ST4 (17.7%), ST1 (8.8%), and ST7, and ST8 (2.9%). As in almost all countries worldwide, ST3 was the most common ST reinforcing the hypothesis of its human origin. Together with a previous preliminary report, a total of seven STs (with the addition of ST5) have been found in Italian symptomatic patients. The wide range of STs identified in the Italian population suggest that Blastocystis sp. infection is not associated with specific STs even if some STs (ST1-ST4) are predominant as reported in all other countries. Since most of the STs identified in Italian patients are zoonotic, our data raise crucial questions concerning the identification of animal reservoirs for Blastocystis sp. and the potential risks of transmission to humans.
