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

Effective adaptive immunity requires generation of a diverse repertoire of antigen receptors via V(D)J recombination. To illuminate the underlying mechanisms, we combined biophysical simulations with experimental data to model chromatin folding and dynamics of the mouse immunoglobulin heavy chain gene (Igh) locus. Simulations that best recapitulated experimental data on locus structure and recombination of Igh alleles identified three novel chromatin folding principles. First, we found that prominent structural features of the Igh locus, such as the 3'-anchored stripe, required cohesin loading throughout the locus. Second, the Eμ enhancer was best modeled as a bi-directional loop extrusion blocker, though it does not bind CTCF. Third, we found that utilization of V
