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

When linear DNAs are injected into Xenopus laevis eggs, they are converted into several different kinds of recombination products. Some molecules undergo homologous recombination by a resection-annealing mechanism; some ends are precisely ligated; and some ends are joined by illegitimate means. The homologous and illegitimate products are also generated in nuclear extracts from stage VI Xenopus oocytes. In order to gain insight into the mechanism(s) of illegitimate end joining, we amplified, cloned and sequenced a number of junctions from eggs and from oocyte extracts. The egg junctions fell into three categories: some with no homology at the join point that may have been produced by blunt-end ligation; some based on small, but significant homologies (5-10 bp); and some with matches of only 1 or 2 nucleotides at the joint. Junctions made in oocyte extracts were largely of the latter type. In the extracts, formation of illegitimate joints required the addition of all four deoxyribonucleoside triphosphates and was inhibited by aphidicolin. This indicates that this process involves DNA synthesis, and mechanisms incorporating this feature are considered. The spectrum of recombination products formed in Xenopus eggs is very reminiscent of those produced from DNA introduced into mammalian cells.
