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

APOBEC2 is a well-conserved member of the AID/APOBEC family of cytidine deaminases. Most members of the family catalyze the conversion of cytosine to uracil either in DNA or RNA, thereby acting as DNA mutators and/or RNA editors. APOBEC2 is the only family member that appears to be catalytically inactive. Instead, its ability to bind, but not deaminate DNA, has been co-opted into a transcription-factor-like functionality. APOBEC2 is highly expressed in skeletal muscle, where it functions to promote and maintain muscle identity by suppressing nonmuscle genes. APOBEC2 is also expressed in several cell types within the hematopoietic lineage. Here, we show that loss of APOBEC2 disrupts proper lymphoid lineage differentiation, resulting in the emergence of lymphoid cells expressing both TCRs and BCRs, as well as additional markers that define a mixed T and B cell identity in both mice with a depletion in
