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

The fornicata (fornicates) is a eukaryotic group known to consist of free-living and parasitic organisms. Genome datasets of two model fornicate parasites Giardia intestinalis and Spironucleus salmonicida are well annotated, so far. The nuclear genomes of G. intestinalis assemblages and S. salmonicida are small in terms of the genome size and simple in genome structure. However, an ancestral genomic structure and gene contents, from which genomes of the fornicate parasites have evolved, remains to be clarified. In order to understand genome evolution in fornicates, here, we present the draft genome sequence of a free-living fornicate, Kipferlia bialata, the divergence of which is earlier than those of the fornicate parasites, and compare it to the genomes of G. intestinalis and S. salmonicida. Our data show that the number of protein genes and introns in K. bialata genome are the most abundant in the genomes of three fornicates, reflecting an ancestral state of fornicate genome evolution. Evasion mechanisms of host immunity found in G. intestinalis and S. salmonicida are absent in the K. bialata genome, suggesting that the two parasites acquired the complex membrane surface proteins on the line leading to the common ancestor of G. intestinalis and S. salmonicida after the divergence from K. bialata. Furthermore, the mitochondrion related organelles (MROs) of K. bialata possess more complex suites of metabolic pathways than those in Giardia and in Spironucleus. In sum, our results unveil the process of reductive evolution which shaped the current genomes in two model fornicate parasites G. intestinalis and S. salmonicida.
