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

A group of hybridomas that express antibodies with related specificities for the influenza virus hemagglutinin (HA), that represent B cells that were the clonal progeny of a single pre-B cell, and that utilized distinct L chain gene rearrangements have been characterized. The clonal relationship was established by the sharing of H chain gene rearrangements at both the productive and the nonproductive alleles. Among these hybridomas, one group had rearranged only one of its kappa alleles, having joined a V kappa 24 gene to the J kappa 2 gene segment. The other group utilized the same V kappa 24 gene segment in productive rearrangement to the J kappa 5 gene segment, and shared an aberrant rearrangements among members of the same B cell clone can normally occur, and can contribute to the generation and diversification of the immune repertoire that is available for the recognition of foreign antigens. Mechanisms by which the distinct rearrangements expressed by the hybridomas might have been generated are discussed.
