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

Genetic linkage maps are critical for assembling draft genomes to a meaningful chromosome level and for deciphering the genomic underpinnings of biological traits. The estimates of recombination rates derived from genetic maps also play an important role in understanding multiple aspects of genomic evolution such as nucleotide substitution patterns and accumulation of deleterious mutations. In this study, we developed a high-throughput experimental approach that combines fluorescence-activated cell sorting, whole-genome amplification, and short-read sequencing to construct a genetic map using single-sperm cells. Furthermore, a computational algorithm was developed to analyze single-sperm whole-genome sequencing data for map construction. These methods allowed us to rapidly build a male-specific genetic map for the freshwater microcrustacean Daphnia pulex, which shows significant improvements compared to a previous map. With a total of mapped 1672 haplotype blocks and an average intermarker distance of 0.87 cM, this map spans a total genetic distance of 1451 Kosambi cM and comprises 90% of the resolved regions in the current Daphnia reference assembly. The map also reveals the mistaken mapping of seven scaffolds in the reference assembly onto chromosome II by a previous microsatellite map based on F2 crosses. Our approach can be easily applied to many other organisms and holds great promise for unveiling the intragenomic and intraspecific variation in the recombination rates.
