First mitochondrial genomes in the Effusa clade (Gastropoda, Ampullariidae): unveiling new insights from Neotropical endemic Pomacea spp.
Article in BMC genomics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPomacea is the most diverse genus of the freshwater snail family Ampullariidae, which have been proposed as model organisms in biogeography, speciation and invasive biology. While substantial effort has been put into the mitochondrial genomes of Pomacea clades associated with invasive species (P. canaliculata and P. bridgesii groups), comparatively little is known about the mitogenomic organization and structure within the Effusa clade.
resultsThis study provides the first complete and annotated mitochondrial genomes of the Effusa clade, based on Pomacea nobilis (Reeve, 1856) and a putative undescribed Pomacea lineage (hereafter Pomacea sp.). The mitochondrial genome of P. nobilis (16,279 - 16,471 bp) and Pomacea sp. (16,355 bp) are among the largest recorded for Pomacea and contain the typical 37 animal genes. A comparative analysis with other Ampullariidae revealed that the Effusa clade differs from both P. canaliculata and P. bridgesii clades mainly by the higher proportion of intergenic regions, the size of many genes (ATP8, ATP6, NAD6, COIII and NAD2), the largest ribosomal RNAs among Pomacea and a putative large repetitive unit in the control region.
conclusionThese findings highlight the distinctiveness of Effusa clade mitogenomes in comparison with the P. canaliculata and P. bridgesii groups. Further mitogenomic studies on underexplored Pomacea lineages will be important to broaden our understanding of mitochondrial genome diversity among apple snails.
