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

It has been believed that the peripheral lymphocytes in chickens proliferate by self-renewing amplification of the preimmune repertoire generated in bursa. We amplified rearranged immunoglobulin variable (V) region genes from the single germinal centers induced by immunization. The sequence analysis of these genes revealed that most were derived from distinct B-cell clones which expanded locally, generating somatic antibody mutants at a high rate. Somatic hypermutations included unlinked base changes and the linked base modifications interpreted as unidirectional transfer of sequences from V region pseudogenes. This finding demonstrates the ongoing post-bursal diversification of B-cells in splenic germinal centers by templated gene conversion as well as untemplated point mutations.
