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

To study inherent properties of somatic hypermutation of human immunoglobulin genes in the absence of antigen selection, mutations of human non-productive VH6 rearrangements enriched by subtractive hybridization were characterized. Ten unique clones arising from nine non-productive rearrangements were isolated. The frequency of mutation was 3.0%. Analysis of these mutations showed intrinsic bias for transitions and cytosine (C) to guanine (G) and G to C transversions. Bias for the strand of DNA targeted by mutation was not evident. Replacement mutations in the complementarity-determining region (CDR) occurred more frequently than expected based on the primary DNA sequence. This targeting of replacement mutations to the CDR may explain the conservation of the VH6 sequence in primates.
