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

Replication-independent histone variants play an essential role in postmitotic neurons. Here, we review how the subtle sequence differences of histone variants compared to their canonical counterparts underly neuronal function. We focus on variants H3.3, H2A.Z, H2A.X, macroH2A, and H2BE; all of which contain divergent sequences that coordinate a diverse set of outcomes. In particular, we highlight their role in neuronal development, plasticity, and memory, with an emphasis on how single amino acid changes can mediate these complex functions. Lastly, we comment on an emerging field of study evaluating the link between histone variants and neurological disorders. Future studies of histone variants will be important to furthering our understanding of neuronal function.
