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

Evidence for gene conversion or unequal double crossover in the human lambda light chain immunoglobulin locus is presented. The high level of J2C2-J3C3 intron cross-hybridization, the identity of the J lambda and J lambda 3 coding and intron sequences, the presence of multiple base differences between the C lambda 2 and C lambda 3 coding regions, and the presence of both the unconverted and converted alleles in the normal gene pool, suggest that a recombinational event has resulted in the conversion of the J lambda 2 coding and intron sequences to those of J lambda 3 and its flanking sequences. Intergenic exchanges, such as the one described here, may provide a mechanism to maintain sequence homogeneity and functionality among the duplicated members of the human lambda gene family.
