Protein-mediated chromosome pairing of repetitive arrays.
Article in Journal of molecular biology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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.
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
Chromosomally integrated arrays of lacO and tetO operator sites visualized by LacI and TetR repressor proteins fused with GFP (green fluorescent protein) (or other fluorescent proteins) are widely used to monitor the behavior of chromosomal loci in various systems. However, insertion of such arrays and expression of the corresponding proteins is known to perturb genomic architecture. In several cases, juxtaposition of such arrays located on different chromosomes has been inferred to reflect pairing of the corresponding loci. Here, we report that a version of TetR-GFP mutated to disrupt GFP dimerization (TetR-A206KGFP or "TetR-kGFP") abolishes pairing of tetO arrays in vivo and brings spatial proximity of chromosomal loci marked with those arrays back to the wild-type level. These data argue that pairing of arrays is caused by GFP dimerization and thus presents an example of protein-assisted interaction in chromosomes. Arrays marked with another protein, TetR-tdTomato, which has a propensity to form intramolecular dimers instead of intermolecular dimers, also display reduced level of pairing, supporting this idea. TetR-kGFP provides an improved system for studying chromosomal loci with a low pairing background.
