Comparative analysis of mitochondrial genomes in the Ceratocystidaceae reveals highly conserved gene organization despite substantial genome size variation.

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
backgroundComparative studies of mitochondrial genomes can assist in determining evolutionary and phylogenetic relationships. In the Ceratocystidaceae fungal family, mitochondrial genomes from only two genera are publicly available. In this study, mitochondrial genomes from 10 genera in Ceratocystidaceae were characterised and comparatively analysed.
resultsMitochondrial (mt) genomes were fully assembled and characterized for 18 species and 10 genera of the Ceratocystidaceae. These mt genomes displayed a remarkable level of diversity owing to the variation in the intergenic regions and intron, both in size and number. Despite large variation in size, these mt genomes displayed high levels of synteny and sequence conservation in the oxidative phosphorylation (OXPHOS) genes and the ribosomal RNA and tRNA genes. The genes are found in identical order and orientation in all mt genomes characterized and the coding sequence of all the OXPHOS genes are highly conserved. Phylogenetic analysis of mitochondrial and nuclear DNA sequences reveals significant differences in evolutionary relationships among species and genera of Ceratocystidaceae.
conclusionThe remarkable variation in mt genome sizes in species of the Ceratocystidaceae is due to the variation observed in the intergenic regions and intron size and number in the conserved protein-coding genes. The gene order and content are identical across all species investigated.
