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

Gene conversion, sometimes also called micro gene conversion or gene conversion-like events, has been proposed to act on a number of genes in higher eukaryotes, such as gamma-globin, beta-tubulin, major urinary protein, and amyloid A genes. In the immune system, immunoglobulin genes and major histocompatibility complex class I and class II genes have been implicated. The notion that integral segments of DNA have been transferred from one gene to another in these cases has, however, met considerable resistance. We have devised a PCR assay detecting only the molecule that results if the E beta d-derived fragment analogous to that introduced in the bm12 mutation is transferred to the A beta k gene. We have proceeded to analyze sperm from the F1 cross C3H/HeJ (haplotype k) x BALB/c (haplotype d). In our assay, we find that the frequency for conversion of this particular DNA segment is 2 x 10(-6). This frequency is relevant only in the germ line; when liver cells were tested as an example of somatic cells, no events were observed, implying a frequency of < 2 x 10(-8) in liver. Fragments > 100 bp seem to be possible to transfer in this conversion.
