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

backgroundAs an important perennial herb in the Iridaceae family, Iris lactea shows strong resistance to saline-alkali, drought, and cold stress, possessing significant ecological, medicinal, and economic value. In this study, we assembled the complete mitochondrial genome of I. lactea using whole-genome sequencing data. METHODS AND

resultsThe assembled genome was 449,819 bp in length (GenBank Accession: PX667947) with a GC content of 46.97%. We found 113 simple sequence repeats, with tetranucleotide motifs being the most common (56, or 49.56%). The genome contains 600 dispersed repeats, consisting of 288 palindromic and 312 forward sequences. This mitogenome contains 36 protein-coding genes with a combined length of 32,343 bp. Analysis of codon usage revealed a strong preference for arginine, leucine, and serine, whereas methionine and tryptophan were infrequently used. We identified 556 RNA-editing sites, all exhibiting cytosine-to-uracil transitions. Analysis of the sequences inserted into the mitochondrial genome revealed that these chloroplast-derived fragments integrated into non-coding IGS regions and rRNA genes.

conclusionsThe successful assembly and analysis of the Iris lactea mitogenome significantly enrich the genomic resources of the genus Iris, providing a solid foundation for future research on phylogenetic evolution, germplasm conservation, and genetic improvement of this genus.
