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

backgroundLaetiporus ailaoshanensis is a fungus within the Laetiporaceae family that causes brown rot in wood through its ability to degrade lignocellulose. However, the mitochondrial genome (mitogenome) of members of the genus Laetiporus has not been extensively investigated.

resultsAfter complete sequencing and assembly, we annotated and characterized the mitogenome of L. ailaoshanensis and selected Polyporales species for comparative analyses, including gene composition and number, AT/GC content, and skew, codon usage, genetic distance, nonsynonymous and synonymous substitution rates (Ka and Ks), intron dynamics, and phylogenetics. The mitogenome of L. ailaoshanensis was found to contain 117,203 bp and 15 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 25 transfer RNA (tRNA) genes, and 12 introns. Phylogenetic analysis based on mitogenomes further confirmed its phylogenetic relationships within Polyporales. Two Laetiporus species were grouped together with Wolfiporia cocos on the same branch and had a high level of support.

conclusionsThis study represents the first report on the mitogenome of L. ailaoshanensis, filling an important gap in the mitogenome database of the Laetiporaceae and providing a cornerstone for comparative genomics within this clade. Additionally, in phylogenetic analysis, the highly supported topological structure clearly placed Laetiporus and Wolfiporia on the same branch, which laid a solid foundation for further clarification of taxonomic classification.
