1 · What the graph read from it

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.

2 · The registry

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

Enterocytozoon bieneusi is a unicellular enteric fungal pathogen and the most common cause of human microsporidiosis. The frequent detection of this organism in animals, including companion animals, livestock and wildlife, has raised the question of the importance of animal reservoirs in the epidemiology of this pathogen. A partial sequence of the ribosomal internal transcribed spacer (ITS) has been widely used as a genetic marker for studying the molecular epidemiology of E. bieneusi. With the aim of comparing E. bieneusi ITS genotypes originating from different host species, and assess the potential for zoonotic transmission, E. bieneusi ITS sequences retrieved from GenBank were analyzed using two metrics of diversity, rarefaction and phylogenetic distance. In spite of the human ITS sample being geographically more diverse, ITS sequence diversity in animals exceeded that of humans. In both host groups much of the ITS diversity remains to be sampled. Using quantitative phylogenetic tests we found evidence for a partial but significant segregation of E. bieneusi ITS sequences according to host species. Host-specific segregation was confirmed by hierarchical analysis of molecular variation. To improve our understanding of the epidemiology of human microsporidiosis and strengthen the study of E. bieneusi populations, efforts to genotype additional E. bieneusi isolates from wildlife and companion animals should be prioritized and the geographic and species diversify of animal samples should be increased. Due to the possibility of genetic recombination in this species, additional unlinked genetic markers need to be developed and included in future studies.
