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

Diabrotica undecimpunctata ssp. howardi, the southern corn rootworm or eastern 12-spotted cucumber beetle, is a generalist insect herbivore that causes damage and yield loss to several crops in North America, including maize. Unresolved phylogenetic relationships within and among D. undecimpunctata subspecies are impacting current quarantine policies. We report the chromosome-level haploid genome assembly, icDiaUnde3, constructed using HiFi and Hi-C read data from a single male D. undecimpunctata collected and identified as subspecies howardi based on geographic location and morphology. The primary 1.74 Gbp assembly contains 11 chromosome-length scaffolds representing 9 autosomes, a single X chromosome, and a supernumerary (B) chromosome (scaffold N50 = 162.8 Mb and L50 = 5). Ab initio and evidence-based structural reference sequence (RefSeq) annotations predicted 18,959 protein-coding genes, in which 99.2% of the 1,367 Benchmark Universal Single-Copy Orthologs from Insecta were complete. Repeat elements occupy 1.26 Gbp (72.33%) of the icDiaUnde3 assembly, with nearly 36% predicted to be retroelements. Alignment of whole chromosomes from icDiaUnde3 with those previously assembled from Diabrotica spp. predicted 2 and 6 autosomal inversions with D. balteata and D. virgifera, respectively. The mitochondrial genome had an annotated gene order and orientation conserved among beetles. The icDiaUnde3 reference genome assembly is a vital resource for taxonomic, comparative, and functional studies to enhance sustainable crop production.
