Analysis of mRNA processing at whole transcriptome level, transcriptomic profile and genome sequence refinement of Trypanosoma cruzi.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 genomic sequence of Trypanosoma cruzi, the protozoan causative of Chagas disease was published more than a decade ago. However, due to their complexity, its complete haploid predicted sequence and therefore its genetic repertoire remains unconfirmed. In this work, we have used RNAseq data to improve the previous genome assembly of Sylvio X10 strain and to define the complete transcriptome at trypomastigote stage (mammalian stage). A total of 22,977 transcripts were identified, of which more than half could be considered novel as they did not match previously annotated genes. Moreover, for the first time in T. cruzi, we are providing their relative abundance levels. We have identified that Sylvio X10 trypomastigotes exhibit a predominance of surface protein genes, specifically those encoding trans-sialidase and mucin-like proteins. On the other hand, detailed analysis of the pre-mRNA processing sites revealed some similarities but also some differences in the spliced leader and different polyadenylation addition sites compared to close related kinetoplastid parasites. Our results also confirm that transcription is bidirectional as occur in other kinetoplastids and the proportion of forward-sense and reverse-sense transcripts is almost equivalent, demonstrating that a strand-specificity does not exist.
