Morphological characterization and HSP70-, IGS-based phylogenetic analysis of two microsporidian parasites isolated from Antheraea pernyi.
Article in Parasitology research, 2017. 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
Two microsporidian isolates were extracted from single infected egg-laying tussah silk moth (Antheraea pernyi) in Liaoning Province, China. The microsporidia were subsequently grown in silk moth larvae, isolated, and subjected to morphological characterization (by light and transmission electron microscopy) and phylogenetic analysis (based on conserved genes). One type of spore was long-axis-oval in shape, measuring 4.71 × 1.95 μm, and the other type was short-axis-oval, measuring 3.64 × 2.17 μm. These dimensions were markedly different from those reported in the spores of the common microsporidia infecting A. pernyi, namely, Nosema pernyi (4.36 × 1.49 μm). A neighbor-joining phylogenetic tree based on HSP70 indicated that these microsporidia belonged to Nosema species and were closely related with Nosema bombycis and Nosema ceranae. Furthermore, in the phylogenetic tree based on the intergenic spacer (IGS) region, the long-axis-oval isolates were closely related and tended to form a clade away from the short-axis-oval isolates and N. pernyi isolates. The microsporidia isolated from A. pernyi clustered in one group. Nosema bombycis, Nosema spodopterae, and Endoreticulatus spp. appeared to be genetically distant from N. pernyi. The two isolates from A. pernyi fell in the Nosema group, but their spores differed from those of the spores of the common A. pernyi parasite N. pernyi, both in morphological and genetic aspects. The two isolates were designated Nosema sp. Ap (L) and Nosema sp. Ap (S). IGS was found to be informative in ascertaining phylogenetic relationships among species, and even closely related strains, of microsporidia.
