Characterization of the mitochondrial genome of an ancient amphipod Halice sp. MT-2017 (Pardaliscidae) from 10,908 m in the Mariana Trench.
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 9 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
Small amphipods (Halice sp. MT-2017) with body length <1 cm were collected from the Challenger Deep (~10,920 m below sea level). The divergence time of their lineage was approximately 109 Mya, making this group ancient compared to others under study. The mitochondrial genome of Halice sp. shared the usual gene components of metazoans, comprising 13 protein coding genes (PCGs), 22 transfer RNAs (tRNAs), and 2 ribosomal RNAs (rRNAs). The arrangement of these genes, however, differed greatly from that of other amphipods. Of the 15 genes that were rearranged with respect to the pancrustacean gene pattern, 12 genes (2 PCGs, 2 rRNAs, and 8 tRNAs) were both translocated and strand-reversed. In contrast, the mitochondrial genomes in other amphipods never show so many reordered genes, and in most instances, only tRNAs were involved in strand-reversion-coupled translocation. Other characteristics, including reversed strand nucleotide composition bias, relatively higher composition of non-polar amino acids, and lower evolutionary rate, were also identified. Interestingly, the latter two features were shared with another hadal amphipod, Hirondellea gigas, suggesting their possible associations with the adaptation to deep-sea extreme habitats. Overall, our data provided a useful resource for future studies on the evolutionary and adaptive mechanisms of hadal faunas.
