Comparative mitogenomic analysis and phylogeny of Veneridae with doubly uniparental inheritance.

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
Doubly uniparental inheritance (DUI) is an atypical animal mtDNA inheritance system, reported so far only in bivalve species, in which two mitochondrial lineages exist: one transmitted through the egg (F-type) and the other through the sperm (M-type). Although numerous species exhibit this unusual organelle inheritance, it is primarily documented in marine and freshwater mussels. The distribution, function and molecular evolutionary implications of DUI in the family Veneridae, however, remain unclear. Here, we investigated 17 species of Veneridae, compared mitochondrial genomes of DUI species and reconstructed their phylogenetic framework. Different sex-linked mitochondrial genomes have been identified in the male gonads and adductor muscles of 7 venerids, indicating the presence of DUI in these species. Analysis of the unassigned regions (URs) of the mitochondrial genome in DUI species revealed that 13 out of 44 URs contained repetitive sequences, with nine being long unassigned regions (LURs). All LURs were capable of forming secondary structures, and most of them exhibited patterns of significant sequence similarity to elements known to have specific functions in the control regions of sea urchins and mammals. The F/M phylogeny showed that DUI venerids exhibit both taxon-specific patterns and gender-specific patterns, with
