Compartmentalization of functions and predicted miRNA regulation among contiguous regions of the nematode intestine.
Article in RNA biology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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 intestine of parasitic nematodes has proven an important target for therapies aimed at prevention and treatment of diseases caused by these pathogens in humans, animals and plants. We have developed a unique research model with the intestine of Ascaris suum, the large round worm of swine and humans, that will enhance biological research on this tissue. To expand utility of this model, we quantitatively compared expression of 15,382 coding RNAs and 277 noncoding, micro RNAs (miRNAs) among 3 contiguous regions of the adult A. suum intestine. Differentially expressed transcripts were identified among regions, with the largest number expressed at significantly higher levels in the anterior region, identifying this region as the most functionally unique compared to middle and posterior regions. We further identified 64 exon splice variants (from 47 genes) that are differentially expressed among these regions. A total of 2,063 intestinal mRNA transcripts were predicted to be targeted by intestinal miRNA, and negative correlation coefficients for miRNA:mRNA abundances predicted 22 likely influential miRNAs and 503 likely associated miRNA:mRNA pairs. A. suum intestinal miRNAs were identified that are conserved with intestinal miRNAs from C. elegans (10 mature sequences and 13 seed sequences conserved), and prospective intestinal miRNAs from the murine gastrointestinal nematode, Heligmosomoides polygyrus (5 mature and 11 seeds). Most of the conserved intestinal miRNAs were also high abundance miRNAs. The data provide the most comprehensive compilation of constitutively and differentially expressed genes along the length of the intestine for any nematode species. The information will guide prospective development of many hypotheses on nematode intestinal functions encoded by mRNAs, miRNAs and interactions between these RNA populations.
