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

Down syndrome, the most common form of human intellectual disability, is caused by nondisjunction and chromosome 21 trisomy (T21). Small centromeres have been hypothesized to contribute to its aetiology and studies on mammals suggest that larger centromeres are more efficiently transmitted, yet complete sequencing of chromosome 21 (chr21) centromeres has been particularly challenging. Using long-read sequencing, we sequenced and assembled the centromeres from eight families that include a child with free T21 (1 trio, 6 child-mother duos, and 1 singleton) all resulting from maternal meiosis I errors. Two of these families carry the smallest chr21 centromeres (143 and 181 kbp) observed in female individuals to date, exhibiting a ~10.7- and ~19.4-fold centromeric α-satellite higher-order repeat array size difference between the maternally inherited homologs, respectively. In both cases, the longer centromere harbors a poorly defined centromere dip region, marked by DNA hypomethylation, in the proband but not in the mother. A comparison of all proband chr21 centromeres (
