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

A large cis-regulatory landscape is a common feature of vertebrate genomes, particularly at key developmental gene loci with finely tuned expression patterns. Existing genetic tools for surveying large genomic regions of interest spanning over hundreds of kilobases are limited. Here we propose a chromosomal engineering strategy exploiting the local hopping trait of the Sleeping Beauty transposon in the mouse genome. We generated embryonic stem cells with a targeted integration of the transposon vector, carrying an enhancer-detecting lacZ reporter and loxP cassette, into the developmentally critical Pax1 gene locus, followed by efficient local transpositions, nested deletion formation and derivation of embryos by tetraploid complementation. Comparative reporter expression analysis among different insertion/deletion embryos substantially facilitated long-range cis-regulatory element mapping in the genomic neighborhood and demonstrated the potential of the transposon-based approach as a versatile tool for exploration of defined genomic intervals of functional or clinical relevance, such as disease-associated microdeletions.
