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

Both kinetochore function and sister chromatid cohesion can depend upon pericentromere chromatin structure, and factors associated with heterochromatin have been proposed to have general, conserved roles in distinguishing centromeres and pericentromeres and in conferring pericentromere-intrinsic functions. We applied genome-wide sequencing approaches to quantify RNA expression, DNA methylation and histone modification distributions in maize (Zea mays), focusing on two maize chromosomes with nearly fully sequenced centromeres and pericentromeres. Aside from the presence of the Histone H3 variant common to all centromeres, Centromeric Histone H3 (CENH3), we found no RNA expression or chromatin modifications that clearly differentiate pericentromeres from either centromeres or from chromosome arms, nor did we identify an epigenetic signature that accurately predicts CENH3 location. RNA expression and chromatin modification frequencies were broadly associated with distance from centromeres, gradually peaking or dipping toward arms. When interpreted in the context of experimental data from other systems, our results suggest that centromeres may confer essential functions (such as cohesion retention) to flanking sequence regardless of the local heterochromatin profile.
