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

Polyrhachis lamellidens is a temporary socially parasitic ant. The newly mated P. lamellidens queen takes over a colony of several Camponotus ant species and uses the labour of the host workers in the early stages of social parasitism. To facilitate genomic resources for these species, we assembled and annotated the chromosomal genome of P. lamellidens using the 10× Genomics linked-read and Hi-C sequencing, and the draft genome of its host, Camponotus japonicus, using long-read sequencing with the Revio system. The P. lamellidens chromosomal genome assembly is 214.1 Mb, 95.5% BUSCO completeness, and contains 13,703 protein-coding genes. The C. japonicus draft genome assembly is 314.2 Mb, 99.0% BUSCO completeness, and contains 11,207 protein-coding genes. Genome-wide phylogeny and synteny analysis confirmed the phylogenetic position of P. lamellidens and C. japonicus, and a high level of synteny with the genome of both ant species. In addition, P. lamellidens possesses nearly identical chemosensory proteins to its host, C. japonicus, and these genes tended to exhibit higher expression levels in the newly mated queen. The genome assemblies of P. lamellidens and its host C. japonicus provide a valuable resource for the molecular biological and bioinformatic basis for studying the strategy of social parasitism in ants.
