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

Mice expressing the immunoglobulin (Ig) heavy (H) chain variable (V) region from a rearranged V(H)12 gene inserted into the IgH locus generate predominantly B-1 cells, whereas expression of two other V(H) region transgenes (V(H)B1-8 and V(H)glD42) leads to the almost exclusive generation of conventional, or B-2, cells. To determine the developmental potential of B cells bearing two distinct B cell antigen receptors (BCRs), one favoring B-1 and the other favoring B-2 cell development, we crossed V(H)12 insertion mice with mice bearing either V(H)B1-8 or V(H)glD42. B cells coexpressing V(H)12 and one of the other V(H) genes are readily detected in the double IgH insertion mice, and are of the B-2 phenotype. In mice coexpressing V(H)12, V(H)B1-8 and a transgenic kappa chain able to pair with both H chains, double H chain-expressing B-2 cells, and B-1 cells that have lost V(H)B1-8 are generated, whereas V(H)B1-8 single producers are undetectable. These data suggest that B-1 but not B-2 cells are selected by antigenic stimuli in whose delivery BCR specificity and surface density are of critical importance.
