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

The human genome contains numerous large tandem repeats, many of which remain poorly characterized. Here we report a novel transfer RNA (tRNA) tandem repeat on human chromosome 1q23.3 that shows extensive copy number variation with 9-43 repeat units per allele and displays evidence of meiotic and mitotic instability. Each repeat unit consists of a 7.3 kb GC-rich sequence that binds the insulator protein CTCF and bears the chromatin hallmarks of a bivalent domain in human embryonic stem cells. A tRNA containing tandem repeat composed of at least three 7.6-kb GC-rich repeat units reside within a syntenic region of mouse chromosome 1. However, DNA sequence analysis reveals that, with the exception of the tRNA genes that account for less than 6% of a repeat unit, the remaining 7.2 kb is not conserved with the notable exception of a 24 base pair sequence corresponding to the CTCF binding site, suggesting an important role for this protein at the locus.
