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

Induction of switch recombination to the gamma 1 and epsilon immunoglobulin (Ig) heavy chain loci was examined in B cells preactivated with anti-Ig (B lymphoblasts). In B lymphoblasts cultured with interleukin 4 (IL-4), IL-5 induced the accumulation of S micro-S gamma 1 rearrangements, but not epsilon recombination. Thus, IL-5 facilitates switch recombination directed to the gamma 1 heavy chain locus by IL-4, but additional signals are required to drive rearrangements to epsilon. Lipopolysaccharide (LPS), in the presence of IL-4, induced the accumulation of both S micro-S gamma 1 and S micro-S epsilon rearrangements, and cells treated with LPS exhibited 40-50-fold more S micro-S gamma 1 rearrangements than cells cultured with IL-5. Induction of switch recombination was not always associated with secretion of the respective Ig isotype, since concentrations of IL-4 that were sufficient to direct switch recombination to gamma 1 and epsilon in blasts treated with LPS failed to elicit secretion of IgG1 and IgE. These results demonstrate differential requirements for switch recombination to the gamma 1 and epsilon loci, as well as independent regulation of Ig gene rearrangement and secretion of each isotype.
